The ISP Defense Squad Attacks Guardian Story on Internet Slowdowns

Phillip "Speaking as a Customer" Dampier

Phillip “Speaking as a Customer” Dampier

Two defenders of large Internet Service Providers are coming to the defense of the broadband industry by questioning a Guardian article that reported major Internet Service Providers were intentionally allowing a degradation in performance of Content Delivery Networks and other high volume Internet traffic in a dispute over money.

Richard Bennett and Dan Rayburn today both published articles attempting to discredit Battle for the Net’s effort highlighting the impact interconnection disputes can have on consumers.

Rayburn:

On Monday The Guardian ran a story with a headline stating that major Internet providers are slowing traffic speeds for thousands of consumers in North America. While that’s a title that’s going to get a lot of people’s attention, it’s not accurate. Even worse, other news outlets like Network World picked up on the story, re-hashed everything The Guardian said, but then mentioned they could not find the “study” that The Guardian is talking about. The reason they can’t find the report is because it does not exist.

[…] Even if The Guardian article was trying to use data collected via the BattlefortheNet website, they don’t understand what data is actually being collected. That data is specific to problems at interconnection points, not inside the last mile networks. So if there isn’t enough capacity at an interconnection point, saying ISPs are “slowing traffic speeds” is not accurate. No ISP is slowing down the speed of the consumers’ connection to the Internet as that all takes place inside the last mile, which is outside of the interconnection points. Even the Free Press isn’t quoted as saying ISPs are “slowing” down access speed, but rather access to enough capacity at connection points.

Bennett:

In summary, it appears that Battle for the Net may have cooked up some dubious tests to support their predetermined conclusion that ISPs are engaging in evil, extortionate behavior.

It may well be the case that they want to, but AT&T, Verizon, Charter Cable, Time Warner Cable, Brighthouse, and several others have merger business and spectrum auction business pending before the FCC. If they were manipulating customer experience in such a malicious way during the pendency of the their critical business, that would constitute executive ineptitude on an enormous scale. The alleged behavior doesn’t make customers stick around either.

I doubt the ISPs are stupid enough to do what the Guardian says they’re doing, and a careful examination of the available test data says that Battle for the Net is actually cooking the books. There is no way a long haul bandwidth and latency test says a thing about CDN performance. Now it could be that Battle for the Net has as a secret test that actually measures CDNs, but if so it’s certainly a well-kept one. Stay tuned.

The higher line measures speeds received by Comcast customers. The lower line represents speeds endured by AT&T customers, as measured by MLab.

The higher line measures speeds received by Comcast customers connecting to websites handled by GTT in Atlanta. The lower line represents speeds endured by AT&T customers, as measured by MLab.

Stop the Cap! was peripherally mentioned in Rayburn’s piece because we originally referenced one of the affected providers as a Content Delivery Network (CDN). In fact, GTT is a Tier 1 IP Network, providing service to CDNs, among others — a point we made in a correction prompted by one of our readers yesterday.

Both Rayburn and Bennett scoff at Battle for the Net’s methodology, results, and conclusion your Internet Service Provider might care more about money than keeping customers satisfied with decent Internet speeds. Bennett alludes to the five groups backing the Battle for the Net campaign as “comrades” and Rayburn comes close to suggesting the Guardian piece represented journalistic malpractice.

Much was made of the missing “study” that the Guardian referenced in its original piece. Stop the Cap! told readers in our original story we did not have a copy to share either, but would update the story once it became available.

We published our own story because we were able to find, without much difficulty, plenty of raw data collected by MLab from consumers conducting voluntary Internet Health Tests, on which Battle for the Net drew its conclusions about network performance. A review of that data independently confirmed all the performance assertions made in the Guardian story, with or without a report. There are obvious and undeniable significant differences in performance between certain Internet Service Providers and traffic distribution networks like GTT.

So let’s take a closer look at the issues Rayburn and Bennett either dispute or attempt to explain away:

  1. MLab today confirmed there is a measurable and clear problem with ISPs serving around 75% of Americans that apparently involves under-provisioned interconnection capacity. That means the connection your ISP has with some content distributors is inadequate to handle the amount of traffic requested by customers. Some very large content distributors like Netflix increasingly use their own Content Delivery Networks, while others rely on third-party distributors to move that content for them. But the problem affects more than just high traffic video websites. If Stop the Cap! happens to reach you through one of these congested traffic networks and your ISP won’t upgrade that connection without compensation, not only will video traffic suffer slowdowns and buffering, but so will traffic from every other website, including ours, that happens to be sent through that same connection.

MLab: "Customers of Comcast, Time Warner Cable, and Verizon all saw degraded performance [in NYC] during peak use hours when connecting across transit ISPs GTT and Tata. These patterns were most dramatic for customers of Comcast and Verizon when connecting to GTT, with a low speed of near 1 Mbps during peak hours in May. None of the three experienced similar problems when connecting with other transit providers, such as Internap and Zayo, and Cablevision did not experience the same extent of problems."

MLab: “Customers of Comcast, Time Warner Cable, and Verizon all saw degraded performance [in NYC] during peak use hours when connecting across transit ISPs GTT and Tata. These patterns were most dramatic for customers of Comcast and Verizon when connecting to GTT, with a low-speed of near 1 Mbps during peak hours in May. None of the three experienced similar problems when connecting with other transit providers, such as Internap and Zayo, and Cablevision did not experience the same extent of problems.”

MLab:

Our initial findings show persistent performance degradation experienced by customers of a number of major access ISPs across the United States during the first half of 2015. While the ISPs involved differ, the symptoms and patterns of degradation are similar to those detailed in last year’s Interconnections study: decreased download throughput, increased latency and increased packet loss compared to the performance through different access ISPs in the same region. In nearly all cases degradation was worse during peak use hours. In last year’s technical report, we found that peak-hour degradation was an indicator of under-provisioned interconnection capacity whose shortcomings are only felt when traffic grows beyond a certain threshold.

Patterns of degraded performance occurred across the United States, impacting customers of various access ISPs when connecting to measurement points hosted within a number of transit ISPs in Atlanta, Chicago, Los Angeles, New York, Seattle, and Washington, D.C. Many of these access-transit ISP pairs have not previously been available for study using M-Lab data. In September, 2014, several measurement points were added in transit networks across the United States, making it possible to measure more access-transit ISP interconnection points. It is important to note that while we are able to observe and record these episodes of performance degradation, nothing in the data allows us to draw conclusions about who is responsible for the performance degradation. We leave determining the underlying cause of the degradation to others, and focus solely on the data, which tells us about consumer conditions irrespective of cause.

Rayburn attempts to go to town highlighting MLab’s statement that the data does not allow it to draw conclusions about who is responsible for the traffic jam. But any effort to extend that to a broader conclusion the Guardian article is “bogus” is folly. MLab’s findings clearly state there is a problem affecting the consumer’s Internet experience. To be fair, Rayburn’s view generally accepts there are disputes involving interconnection agreements, but he defends the current system that requires IP networks sending more traffic than they return to pay the ISP for a better connection.

Rayburn's website refers to him as "the voice of industry."

Rayburn’s website refers to him as “the voice of industry.”

  1. Rayburn comes to the debate with a different perspective than ours. Rayburn’s website highlights the fact he is the “voice of the industry.” He also helped launch the industry trade group Streaming Video Alliance, which counts Comcast as one of its members. Anyone able to afford the dues for sponsor/founding member ($25,000 annually); full member ($12,500); or supporting member ($5,500) can join.

Stop the Cap! unreservedly speaks only for consumers. In these disputes, paying customers are the undeniable collateral damage when Internet slowdowns occur and more than a few are frequently inconvenienced by congestion-related slowdowns.

It is our view that allowing paying customers to be caught in the middle of these disputes is a symptom of the monopoly/duopoly marketplace broadband providers enjoy. In any industry where competition demands a provider deliver an excellent customer experience, few would ever allow these kinds of disputes to alienate customers. In Atlanta, Los Angeles, and Chicago, for example, AT&T has evidently made a business decision to allow its connections with GTT to degrade to just a fraction of the performance achieved by other providers. Nothing else explains consistent slowdowns that have affected AT&T U-verse and DSL customers for months on end that involve GTT while Comcast customers experience none of those problems.

We also know why this is happening because AT&T and GTT have both confirmed it to Ars Technica, which covered this specific slowdown back in March. As is always the case about these disputes, it’s all about the money:

AT&T is seeking money from network operators and won’t upgrade capacity until it gets paid. Under its peering policy, AT&T demands payment when a network sends more than twice as much traffic as it receives.

“Some providers are sending significantly more than twice as much traffic as they are receiving at specific interconnection points, which violates our peering policy that has been in place for years,” AT&T told Ars. “We are engaged in commercial-agreement discussions, as is typical in such situations, with several ISPs and Internet providers regarding this imbalanced traffic and possible solutions for augmenting capacity.”

competitionMissing from this discussion are AT&T customers directly affected by slowdowns. AT&T’s attitude seems uninterested in the customer experience and the company feels safe stonewalling GTT until it gets a check in the mail. It matters less that AT&T customers have paid $40, 50, even 70 a month for high quality Internet service they are not getting.

In a more competitive marketplace, we believe no ISP would ever allow these disputes to impact paying subscribers, because a dissatisfied customer can cancel service and switch providers. That is much less likely if you are an AT&T DSL customer with no cable competition or if your only other choice cannot offer the Internet speed you need.

  1. Consolidating the telecommunications industry will only guarantee these problems will get worse. If AT&T is allowed to merge with DirecTV and expand Internet service to more customers in rural areas where cable broadband does not reach, does that not strengthen AT&T’s ability to further stonewall content providers? Of course it does. In fact, even a company the size of Netflix eventually relented and wrote a check to Comcast to clear up major congestion problems experienced by Comcast customers in 2014. Comcast could have solved the problem itself for the benefit of its paying customers, but refused. The day Netflix’s check arrived, problems with Netflix magically disappeared.

More mergers and more consolidation does not enhance competition. It entrenches big ISPs to play more aggressive hardball with content providers at the expense of consumers.

Even Rayburn concedes these disputes are “not about ‘fairness,’ it’s business,” he writes. “Some pay based on various business terms, others might not. There is no law against it, no rule that prohibits it.”

Battle for the Net’s point may be that there should be.

Cablevision Gives Free Optimum Online Speed Boost to 25Mbps

Phillip Dampier June 23, 2015 Broadband Speed, Cablevision (see Altice USA), Consumer News Comments Off on Cablevision Gives Free Optimum Online Speed Boost to 25Mbps

Optimum-Branding-Spot-New-LogoCablevision has treated its broadband subscribers to a free speed boost for those signed up for the basic Optimum Online Internet tier. The old speed of 15/5Mbps has today been raised to 25/5Mbps, meeting the FCC’s minimum speed to qualify as broadband service.

Cablevision continues to sell its base Internet service at a non-promotional price of $39.99/month, considerably lower than most other cable operators.

“We are taking the next step as New York’s premiere connectivity company to provide a better, faster data experience both inside and outside the home at no additional cost,” Kristin Dolan, chief operating officer of Cablevision, said in a statement. “This speed increase, along with Optimum WiFi, provides a superior broadband experience to meet and exceed the needs of our customers.”

For now, Cablevision’s other widely available broadband tiers: Optimum Online Ultra 50, Optimum Online Ultra 75 and Optimum Online Ultra 101 are unchanged.

FCC Likely to Toss First Formal Net Neutrality Complaint Against Time Warner Cable

Phillip Dampier June 23, 2015 Consumer News, Net Neutrality, Online Video, Public Policy & Gov't Comments Off on FCC Likely to Toss First Formal Net Neutrality Complaint Against Time Warner Cable

The nation’s first Net Neutrality complaint filed with the Federal Communications Commission accuses Time Warner Cable of refusing to provide the best possible path for its broadband customers to watch a series of high-definition webcams covering San Diego Bay.

sundiego_banner

Commercial Network Services’ CEO Barry Bahrami wrote the FCC that Time Warner Cable is degrading its ability to exercise free expression by choosing which Internet traffic providers it directly peers with and which it does not:

I am writing to initiate an informal complaint against Time Warner Cable (TWC) for violating the “No Paid Prioritization” and “No Throttling” sections of the new Net Neutrality rules for failure to fulfill their obligations to their BIAS consumers by opting to exchange Internet traffic over higher latency (and often more congested) transit routes instead of directly to the edge provider over lower latency peering routes freely available to them through their presence on public Internet exchanges, unless a payment is made to TWC by the edge provider. These violations are occurring on industry recognized public Internet peering exchanges where both autonomous systems maintain a presence to exchange Internet traffic, but are unable to due to the management policy of TWC. As you know, there is no management policy exception to the No Paid Prioritization rule.

By refusing to accept the freely available direct route to the edge-provider of the consumers’ choosing, TWC is unnecessarily increasing latency and congestion between the consumer and the edge provider by instead sending traffic through higher latency and routinely congested transit routes. This is a default on their promise to the BIAS consumer to deliver to the edge and make arrangements as necessary to do that.

Bahrami’s complaint deals with interconnection issues, which are not explicitly covered by the FCC’s Net Neutrality rules that prohibit intentional degradation or paid prioritization of network traffic. For years, ISPs have agreed to “settlement-free peering” arrangements with bandwidth providers that exchange traffic in roughly equal amounts with one another. To qualify for this kind of free interconnection arrangement, CNS’ webcams must be hosted by a company that receives about as much traffic from Time Warner Cable customers as it sends back to them — an unlikely prospect.

As bandwidth intensive content knocks traffic figures out of balance, ISPs have started demanding financial compensation from content producers if they want performance guarantees. This is what led Comcast, Verizon and AT&T to insist on paid interconnection agreements with the traffic monster Netflix.

Time Warner Cable is calling on the FCC to dismiss Bahrami’s letter on the grounds it is not a valid Net Neutrality complaint.

“[The FCC should] reject any complaint that is premised on the notion that every edge provider around the globe is entitled to enter into a settlement-free peering arrangement,” Time Warner Cable responds. That is a nice way of telling CNS it doesn’t get a premium pathway to Time Warner Cable customers for free just because of Net Neutrality rules.

CNS250X87Bahrami responds Time Warner’s attitude is based on a distinction without much difference because he is effectively being told CNS must pay extra for a suitable connection with Time Warner to guarantee his web visitors will have a good experience.

“This is not a valid complaint, and there is no way the FCC is going to side with them,” Dan Rayburn, a telecom analyst at Frost & Sullivan and the founding member of the Streaming Video Alliance told Motherboard. “The rules say you can’t block or throttle, but there’s no rule that says Time Warner Cable has to give CNS settlement-free peering. I don’t see how the FCC could possibly say there’s a violation here.”

The FCC made it clear in its Net Neutrality policy it intends “to watch, learn, and act as required, but not intervene now, especially not with prescriptive rules” with respect to interconnection matters.

That makes it likely Bahrami’s complaint will either be tossed out on grounds it is not a Net Neutrality violation or more likely dismissed but kept in what will likely be a growing file of future cases of interconnection disputes between ISPs and content producers. If that file grows too large too quickly, the FCC may be compelled to act.

Switzerland Moving Into World’s Top 10: Competition Forces Major Broadband Upgrades

Phillip Dampier June 23, 2015 Broadband Speed, Charter Spectrum, Competition, Consumer News, Net Neutrality, Video Comments Off on Switzerland Moving Into World’s Top 10: Competition Forces Major Broadband Upgrades

upc_cablecom_logoJohn Malone’s cable systems in Europe share little in common with what Americans get from their local cable company. In Switzerland, Liberty-owned UPC Cablecom charges $95 a month for 250/15Mbps service — a speed Charter Communications customers cannot buy at any price. Liberty is Charter’s biggest investor/partner. Later this month, Swiss cable customers will be able to buy 500Mbps from UPC. When implemented, that is expected to push Switzerland’s broadband speed rankings into the global top-10. Currently Switzerland is rated #11. The United States is #28 and Canada is ranked #34.

UPC’s primary competitor  — telephone company Swisscom — is aggressively upgrading its facilities with its eye on offering G.fast, the latest version of DSL capable of delivering up to 500Mbps across 200-300 meters of old copper phone wiring, making it suitable for fiber to the neighborhood deployments similar to AT&T U-verse or Bell’s Fibe. Swisscom is also expanding fiber to the home service on a more limited basis, offering customers 1,000/1,000Mbps service on that network.

Why all the upgrades? Competition in the Swiss broadband marketplace.

If Swisscom can offer gigabit broadband speeds, then so can UPC Cablecom, claims its CEO Eric Tveter.

“We can offer every customer across the country the same speeds,” Tveter told the Schweiz am Sonntag newspaper. “At the end of June, we will introduce new Internet speeds of 500Mbps. Demand for [fiber’s] symmetrical speeds is still very low among residential customers, but if demand increases we will offer them.”

Customers looking for gigabit speed would likely have to sign up as a commercial customer of UPC for now. But the company is preparing to introduce DOCSIS 3.1 which will allow the existing cable network to easily deliver gigabit speeds to residential customers. In fact, Tveter is looking at introducing 10Gbps speeds in Switzerland in the coming years.

Tveter aggressively criticized some of his biggest competitors for using marketing-speak to promote “new” products UPC already offers.

swisscom_logo_detailSome providers have promoted “cloud-based” on-demand access to video that Tveter says has been available from the cable company for several years.

This year, UPC Swisscom has been reassuring customers it does not allow America’s National Security Agency to spy on its customers and has taken measures to keep Chinese intelligence agents and hackers out of its network. The Swiss courts have made it clear they want nothing to do with NSA spying and permit operators to take any and all steps to keep unauthorized American and Chinese agencies from penetrating Swiss telecommunications.

Tveter points out all Swiss networks use equipment manufactured by U.S. and Chinese companies, but there are no indications either government has forced manufacturers to give back-door access to that equipment for surveillance or espionage purposes.

UPC Cablecom also voluntarily adheres to Net Neutrality principles for its Swiss customers.

AT&T, Verizon, Time Warner Cable Implicated In Content Delivery Network Slowdowns

fat cat attIf your YouTube, Netflix, or Amazon Video experience isn’t what it should be, your Internet Service Provider is likely to blame.

A consumer group today implicated several major Internet providers including Comcast, AT&T, Time Warner Cable and Verizon in an Internet slowdown scheme that prevented customers from getting the broadband performance they are paying for.

A study* of 300,000 Internet users conducted by Battleforthenet found evidence some of America’s largest providers are not adequately providing connectivity for Content Delivery Networks (CDNs) that supply high-capacity traffic coming from the Internet’s most popular websites.

Significant performance degradation was measured on the networks of the five largest American ISPs, which provide Internet connectivity for 75% of U.S. households.

“For too long, Internet access providers and their lobbyists have characterized Net Neutrality protections as a solution in search of a problem,” Tim Karr from Free Press told the Guardian newspaper, which had advance notice of the study. “Data compiled using the Internet Health Test show us otherwise – that there is widespread and systemic abuse across the network. The irony is that this trove of evidence is becoming public just as many in Congress are trying to strip away the open Internet protections that would prevent such bad behavior.”

freepressThe study revealed network performance issues that would typically be invisible to most broadband customers performing generic speed tests to measure their Internet speed. The Open Technology Institute’s M-Lab devised a more advanced speed test that would compare the performance of high traffic CDNs across several providers. CDNs were created to reduce the distance between a customer and the content provider and balance high traffic loads more evenly to reduce congestion. The shorter the distance a Netflix movie has to cross, for example, the less of a chance network problems will disrupt a customer’s viewing.

If technicians controlled the Internet, the story would end there. But it turns out money has gotten between Internet engineers with intentions of moving traffic as efficiently as possible and the executives who want to be paid something extra to carry the traffic their customers want.

That may explain why Comcast can deliver 21.4Mbps median download speeds for traffic distributed by a CDN Tier1 IP network called GTT to customers in Atlanta, while AT&T only managed to squeeze through around 200kbps — one-fifth of 1Mbps. It turns out AT&T’s connection with GTT may be maxed out and AT&T will not upgrade capacity to a network that sends AT&T customers more than twice the traffic it receives from them without direct compensation from GTT.

Internet traffic jam, at least for AT&T customers in Atlanta trying to access content delivered by GTT.

Internet traffic jam, at least for AT&T customers in Atlanta trying to reach content delivered by GTT.

An AT&T U-verse customer in Atlanta would probably not attribute the poor performance depicted in M-Lab’s performance test directly to AT&T because Internet responsiveness for other websites would likely appear normal. Customers might blame the originating website instead. But M-Lab’s performance results shows the trouble is limited to AT&T, not other providers like Comcast.

AT&T: Slow down, you move too fast.

AT&T: Slow down, you move too fast.

The issues of performance and peering agreements that provide enough capacity to meet demand are close cousins of Net Neutrality, which is supposed to prevent content producers from being forced to pay for assurances their traffic will reach end users. But that seems to be exactly what AT&T is asking for from GTT.

“It would be unprecedented and unjustified to force AT&T to provide free backbone services to other backbone carriers and edge providers, as Cogent et al seek,” AT&T wrote in response to a request from several CDNs to disallow AT&T’s merger with DirecTV. “Nor is there any basis for requiring AT&T to augment network capacity for free and without any limits. Opponents’ proposals would shift the costs of their services onto all AT&T subscribers, many of whom do not use Opponents’ services, and would harm consumers.”

* – When a copy of the study becomes publicly available, we will supply a link to it.

Correction: It is more accurate to describe GTT as a “Tier1 IP network” which supplies services to CDN’s, among others. More detail on what GTT does can be found here.
