The ongoing COVID-19 pandemic and corresponding traffic growth has apparently taken its toll on network capacity at Mediacom, forcing the company to reach out to a growing number of its heavy uploaders and telling them to reduce usage or face a speed throttle or the possible closure of their account.

An East Moline, Ill. Mediacom broadband customer of 10 years was offended to receive a phone call from Mediacom’s “Fraud and Abuse Department” telling him he was overusing his gigabit internet account, which includes a 6 TB data cap. The customer was certain he never exceeded Mediacom’s data cap, and in fact recorded 2.5 TB of usage over the last month, well below his data allowance.

Mediacom’s representative explained the problem was not with how much he downloaded.

“He told me my upload was 450 GB over their average and if I didn’t reduce my usage they would either throttle or disconnect me,” DSL Reports‘ reader poonjahb wrote. “I argued that I used less than half of the total data allowed by my plan, but he said my 1.2 TB of upload was too much and that this was my warning.”

Other Mediacom customers across the Midwest also received similar letters in early January, and several contacted Stop the Cap! Many were already annoyed Mediacom had earlier imposed a data cap, but were incensed they were now being threatened when usage was well under that cap.

“I am paying for gigabit internet service just to never have to worry about a data cap,” said Cory, a Mediacom customer in Missouri. “It comes with a 6,000 GB monthly allowance, which is way more than I will ever use, but I still received a warning letter claiming I was uploading too much. I discovered I used about 900 GB over the last two months, setting up a cloud backup of my computer. At most I can send files at around 50 Mbps, which they claim is interfering with other customers in my neighborhood. I don’t understand.”

Several filed complaints with the FCC, which the agency forwarded on to Mediacom customer service. Most received form letter replies.

COVID-19 Pandemic Causes Traffic Surge, Mediacom Tells Stop the Cap!

“Mediacom routinely reviews both download and upload usage trends to determine if any customers are using a disproportionate share of bandwidth compared to average users,” explains Thomas J. Larsen, senior vice president of government and public relations at Mediacom. “If a customer falls into the top 0.5% of downstream or upstream capacity users in a given month, they may receive a letter or call from Mediacom regarding their usage. This would apply to both business and residential customers. The reason for contacting the customers is to explain that their usage patterns may be degrading the performance of the network and affecting other users.”

Larsen pointed to statistics from the cable industry’s largest trade group, NCTA – The Internet & Television Association, which reported a 31.8% total cumulative growth in downstream internet traffic and a 51.1% increase in upstream traffic since the spring COVID-19 lockdowns back in March 2020.

A Mediacom letter sent to customers complaining to the FCC about the practice cited network “stress” caused by excess upstream traffic. Larsen told Stop the Cap! the company regularly reviews customers’ download and upload traffic trends, looking for outliers that use a disproportionate share of bandwidth compared to average users. Larsen would not admit if heavy users were noticeably affecting other customers with congestion-related slowdowns, but said the company was “reaching out … more frequently than before” to the top 0.5% of traffic generating users anyway. He also noted this policy equally applied to both residential and business accounts.

“This is not the easiest topic to explain because internet usage is growing rapidly in this work from home/study from home environment, so it is difficult to give an exact number that puts a customer into the 0.5% category because that number changes from month to month,” Larsen noted. “Understandably, that may make the policy seem arbitrary when we are really just trying to stay in line with moving usage trends.”

Internet Service Providers Have Wide Latitude to Cut Off Heavy Users

Virtually every internet service provider has a provision in their acceptable use policy allowing them to terminate or restrict service when a customer causes problems for that provider. Mediacom is no exception, telling subscribers “without limitation, customer’s usage of the service cannot restrict, inhibit, interfere with or otherwise disrupt or cause disruption, performance degradation of other users or impair or threaten to impair the operation of Mediacom’s systems or network.” This policy is in addition to whatever data usage plans are in place.

But Larsen insists Mediacom is not trying to alienate its customers.

“[We want to] work with our customers to address this issue in a productive manner,” Larsen told Stop the Cap!

At the moment, the only solution seems to be to reduce usage enough to stay off of the company’s “top 0.5%” radar.

Mediacom’s Warning Letters Uncommon Among Other Providers

Mediacom’s crackdown on heavy usage has not been copied by most other U.S. providers. Although traffic growth has been measured by virtually every provider in the country, most providers are mitigating possible service degradation by aggressively upgrading capacity or quietly node splitting neighborhoods experiencing the highest traffic growth, which immediately eases congestion issues.

The company did not indicate if its usage crackdown was temporary or if any planned network upgrades would allow it to ease restrictions sometime in the near future.

Other small providers dealing with congestion issues found a better solution sending letters to high traffic customers explaining forthcoming upgrades and temporarily requesting they limit upstream traffic during peak usage times, while not penalizing them for any off-peak traffic. That might prove to be a useful compromise between Mediacom and its customers and preserve goodwill.

Less than three months before announcing it would acquire Time Warner Cable in a $55 billion deal, Charter Communications quietly dropped usage caps, in place on its broadband plans since 2009, without explanation and the FCC wants to know why.

FCC officials have sent a letter to Charter requesting a range of information about the company’s broadband services, including information about Charter’s since-dropped usage cap program. The federal agency reviewing its buyout of Time Warner Cable wants to know when Charter dropped its usage caps and why.

Charter Communications has promoted “no usage caps” as a selling point to convince regulators its purchase of Time Warner Cable is a consumer-friendly transaction. Charter has promised a cap-free Internet experience for Time Warner Cable customers for three years, but has not committed to offer unlimited broadband service beyond that date.

Two months before Time Warner Cable planned a since-dropped 2009 market test of usage caps in New York, North Carolina and Texas, Charter Communications confirmed it was introducing “monthly residential bandwidth consumption thresholds” on its broadband customers ranging from 100GB for customers with speeds of 15Mbps or slower and 250GB for customers subscribed to 15-25Mbps service.

“In order to continue providing the best possible experience for our Internet customers, later this month we will be updating our Acceptable Use Policy (AUP) to establish monthly residential bandwidth consumption thresholds,” Charter’s Eric Ketzer told DSL Reports at the time. “More than 99% of our customers will not be affected by our updated policy, as they consume far less bandwidth than the threshold allows.”

Few customers realized Charter had placed a cap on Internet usage because the cable company treated the limits as “soft caps” — guidelines they could cite if they found a customer using a very large amount of bandwidth. But customers were not charged overlimit fees and few ever heard from Charter about their usage, even if it well-exceeded their allowance.

In front of Time Warner Cable offices in Rochester, N.Y. protesting Time Warner Cable’s proposed usage caps. (April 2009)

Only a handful of companies, including national providers like AT&T (for DSL) and Comcast (in usage cap market trial areas), have followed up usage allowances with stinging overlimit fees for those exceeding them, applied to customer bills. The practice is far more common among smaller and regional cable companies like Alaska’s GCI, which earned 10 percent of its broadband revenue billing customers for excess usage.

In March of this year, Stop the Cap! reported Charter quietly dropped usage caps (or “thresholds”) from their Acceptable Use Policy, ending six years of usage capped service — less than three months before announcing it was acquiring Time Warner Cable.

Time Warner Cable’s own experience with usage caps was short-lived after Stop the Cap! and other consumer advocates and elected officials launched a protest campaign against Time Warner Cable’s plans to expand a test of usage-based billing beyond Beaumont, Tex. to Rochester, N.Y., Greensboro, N.C., and the cities of Austin and San Antonio in Texas.

Time Warner proposed four tiers of usage allowances: 5, 10, 20, and 40 GB priced from $29.95 to $54.90 a month. The overlimit fee was to be $1/GB. Sanford Bernstein, a Wall Street research firm, predicted an average family subscribed to Time Warner’s top 40GB usage plan would pay around $200 a month in overlimit fees if they used Netflix more than 7.25 hours a week.

Within two weeks of launching protests in the four cities where Time Warner was planning to add caps, the plan was shelved permanently. But many Time Warner Cable customers have remained wary of the company’s plans regarding usage caps. Time Warner’s retooled, optional usage capped tiers offered to customers looking for a discount have proved dismal failures since their introduction, with fewer than 1% of Time Warner customers finding usage-limited Internet access compelling.

Rationing Your Internet Experience?

Consumer advocates also fear usage caps could reappear under Charter as quickly as they disappeared. Stop the Cap! is suspicious of Charter’s time-limited commitment to keep customers free of usage caps for three years. We are lobbying state and federal regulators to permanently extend that commitment as a condition of approving any merger between Charter and Time Warner.

“Customers must be assured they can always choose a reasonably priced unlimited use Internet option,” said the group’s founder Phillip Dampier. “If Charter/Time Warner Cable/Bright House wants to offer optional discounts for customers volunteering to limit their personal use, we are not opposed to that. But based on Time Warner’s own record, you can count on only a few thousand customers willing to voluntarily surrender unlimited, flat rate access.”

Stop the Cap! believes there is no credible reason Internet providers should be imposing compulsory usage caps or usage billing on anyone.

“Broadband is a huge money-maker and the costs to offer it continue to drop even as provider profits rise,” said Dampier. “Rationing broadband with a usage allowance is as credible as rationing Niagara Falls or breathing.”

The FCC is also requesting documentation detailing Charter’s proposed expansion of Wi-Fi hotspots in Time Warner Cable areas and company plans to boost standard broadband speeds from 15Mbps to 60Mbps. Charter has until Oct. 13 to respond.

Charter Communications has quietly dropped usage caps and allowances from the company’s terms and conditions, once again giving Charter broadband customers unlimited access to the Internet.

Like Cox Cable, Charter almost never enforced their usage caps, which were specified as 100GB for its “base” service, 250GB for “Plus” and “Max” tiers and 500GB for “Ultra” service. Customers threatening to cancel service over usage cap matters were assuaged with a commitment by retention specialists that the caps were just a “guideline” and would not be enforced except in the most egregious instances of customer “overuse” of the Internet.

In place of the caps, Charter has returned to boilerplate language found in almost every ISP’s Acceptable Use Policy:

Excessive use of bandwidth that in Charter’s sole opinion, places an unusually large burden on the network or goes above normal usage [is prohibited]. Charter has the right to impose limits on excessive bandwidth consumption via any means available to Charter.

Customers routinely exceeding a terabyte of usage a month have never been contacted by Charter, so such usage apparently does not place a burden on their network. However, Charter also reserves the right to cut your speeds through “reasonable network management tools,” some that may now be forbidden by the FCC’s Net Neutrality policy:

Charter uses a variety of reasonable network management tools and practices consistent with industry standards. In the event the periods of congestion necessitate such management, Charter has available the following tools and practices (without limitation and as may be adjusted over time): (i) use of an upper limit of bandwidth allocated for uploading of files during congested periods; (ii) Subscriber Traffic Management (STM) technology to temporarily lower the priority of traffic with the greatest impact on peak congestion; (iii) spam filtering and detection techniques; and (iv) measures to protect the security and integrity of its network, resources and subscribers. In limited instances if employed, these techniques may affect the throughput rate at which subscribers may send and receive data, the ability of users to establish session connections within the network, or result in the delay of certain traffic during times of peak congestion.

Charter has “simplified” their Internet offers down to two for most customers: 60/4Mbps for Spectrum Internet ($59.99) and 100/5Mbps for Internet Ultra ($109.99). A source at Charter tells Stop the Cap! the company is conducting very limited trials raising speeds to 100/25Mbps for its base package and boosting its Ultra tier to 300/50Mbps, in case fiber competitors arrive. Those tests are not expected to become widespread however as the prevailing view at Charter is to wait until it deploys DOCSIS 3.1 and then raise speeds to 300/50Mbps for its entry-level package and 500/300Mbps for Ultra.

Starting in January, Charter began notifying its broadband-only customers it was raising prices $5 a month (from $54.99 to $59.99).

Comcast has strongly denied reports it threatened customers with service termination for using the Tor anonymous web browser, designed to obscure a web user’s identity or location.

Over the weekend, Deep.Dot.Web reported that Comcast agents were contacting customers using the Tor web browser and warned them their Internet access was in peril if they continued using the anonymous browsing software, claiming it was against Comcast’s acceptable use policy.

Allegedly, Comcast representatives “Jeremy” and “Kelly” claimed Tor was “an illegal service” and demanded the customers reveal the web sites they were attempting to reach using the browser.

The representative identified as “Kelly” claimed:

“Users who try to use anonymity, or cover themselves up on the Internet, are usually doing things that aren’t so-to-speak legal. We have the right to terminate, fine, or suspend your account at anytime due to you violating the rules. Do you have any other questions? Thank you for contacting Comcast, have a great day.”

The Tor browser was designed to protect the identity of its privacy-minded users from nosy government agencies and law enforcement elements, but has also been used to hide illegal activities ranging from child pornography and drug dealing to murder-for-hire and espionage-related activities. But the majority of the estimated four million Tor users rely on the browser primarily to help them overcome Internet censorship blocks or geographic restrictions on online video content.

Tor directs each user’s Internet traffic through a free, worldwide, volunteer network of more than five thousand relays to hide a user’s location and usage from anyone conducting network surveillance or traffic analysis. Technically, users who volunteer to run a relay may be in violation of Comcast’s acceptable use policy, which states (in part):

[Customers may not] use or run dedicated, stand-alone equipment or servers from the Premises that provide network content or any other services to anyone outside of your Premises local area network (“PremisesLAN”), also commonly referred to as public services or servers. Examples of prohibited equipment and servers include, but are not limited to, email, web hosting, file sharing, and proxy services and servers.

But whether the messages reported by Deep.Dot.Web were simply the result of an overeager support employee or actual company policy is now in dispute.

Comcast emphatically denied the customer contacts reported by Deep.Dot.Web ever took place and claimed Comcast has no restrictions on customers using the Tor browser.

“The anecdotal chat room evidence provided is not consistent with our agents’ messages and is not accurate,” said Comcast’s Charlie Douglas. “Per our own internal review, we have found no evidence that these conversations took place, nor do we employ a Security Assurance team member named Kelly. Comcast doesn’t monitor users’ browser software or web surfing, and has no program addressing the Tor browser. Customers are free to use their XFINITY Internet service to visit any website or use it however they wish.”

A company blog post this morning broadened the company’s denials:

Comcast is not asking customers to stop using Tor, or any other browser for that matter. We have no policy against Tor, or any other browser or software. Customers are free to use their Xfinity Internet service to visit any website, use any app, and so forth.

Here are the facts:

• Comcast doesn’t monitor our customer’s browser software, web surfing or online history.
• The anecdotal chat room evidence described in these reports is not accurate.
• We respect customer privacy and security and only investigate and disclose certain information about a customer’s account with a valid court order or other appropriate legal process, just like other ISPs. More information about these policies can be found in our Transparency Report here.
• We do not terminate customers for violating the Copyright Alert System (aka “six strikes”), which is a non-punitive, educational and voluntary copyright program. Read more here.

Some Clearwire customers remain unhappy when speeds are throttled to “manage” the network.

Clear (formerly known as Clearwire) has announced a general rate increase of about 10 percent for customers using its legacy 4G WiMAX broadband service.

As a result, most customers will pay about $5 more per month for fixed wireless or “on the go” broadband service.

“We instituted this to remain competitive and manage our costs,” a Sprint representative told Broadcasting & Cable. “Like our competitors, we must respond to customer trends, and provide a good user experience, and as a result we will make adjustments to fees and services from time to time. Our offer is still comparable to other offerings in the marketplace.”

Some customers would argue with Sprint’s definition of a “good user experience,” as complaints continue about heavy-handed throttling of Clear’s service that makes high bandwidth applications painful or impossible to use in the evening.

Stop the Cap! reader Akos contacted us this week to complain Clear still advertises and contracts for “unlimited data and top speeds,” while not exactly being upfront about targeting certain traffic for a prime time speed throttle that effectively keeps customers from streaming video.

“They openly admit their service is being throttled by software at each tower site that activates when it detects streaming video services like Netflix, reducing speed from 1.3Mbps to as little as 20kbps, rendering it unusable,” said Akos.

The speed throttle is usually active from 8pm-1:30am daily, when traffic is anticipated to be highest. Clear speaks about its network management speed throttle in the fine print: its Acceptable Use Policy.

Akos complains Clear’s speed throttle makes it easy to blame the streaming service, not Clear itself, because customers running speed tests will not see throttled speeds.

“It fools people to think the problem is on their end or with the streaming service, so customers don’t complain to Clear,” says Akos.

As a result, people using streaming video services get about 30 seconds of uninterrupted video before the throttle kicks in bringing extensive buffering delays.

Clearwire’s Speed Throttle Subject of Lawsuits

Clear’s own 2010 marketing promises unlimited usage with no speed reductions, like those “other” providers.

Clearwire’s speed throttle has been a part of life with the wireless service since 2010. Clearwire had significant legal exposure over its choice of network management because the company routinely advertised “unlimited service” with no speed throttles or overlimit fees. At least three lawsuits were filed against the company for its undisclosed throttling practices, eventually condensed into a single class action case that was finally settled last month.

Under the terms of the settlement, Clear admits no wrongdoing, but will clearly disclose it uses “network management” practices — a term that generally means usage caps and/or speed throttles — and will give customers information about the speeds they can expect when the throttle is active. As of today, Clear has not done that. Clear also volunteered to suspend term contracts and waive early termination fees for customers complaining about speed issues.

At least seven law firms handling the case will split a total award fee of $1,887,792.91 and expenses of $62,207.09. Individual representative plaintiffs each receive up to $2,000. Everyone else identified as part of the class action case that returned a claim form prior to Jan. 3, will receive an average of less than $30:

• a 50% refund of any early termination fee charged after a customer canceled service because of speed throttling;
• a rebate of $14 for customers signing up for Clearwire before Sept. 1, 2010 and experiencing speed throttling or a rebate of at least $7 for Clearwire customers signing up on or after Sept. 1, 2010;
• plus varying amounts for each month of service prior to Feb. 27, 2012 during which Clearwire’s records show it throttled a customer’s Internet speed. Customers throttled at 0.25Mbps will receive $5.00 for each month throttled, 0.60 Mbps: $3.00, and 1.0 Mbps: $2.00.

Court documents reveal of the 2,733,406 customers identified in Clearwire’s records as being speed throttled, only 83,840 submitted timely claims as part of the class action case. This represents a claims rate of about 3.1%. Of those, 76,199 were for speed throttling, 2,331 were requests for reimbursement of early termination fees.

The Future of Clear’s WiMAX and Sprint’s 4G

Sprint purchased the assets of Clearwire Corporation in July, rebranded the network “Clear,” and as of the end of August, stopped selling WiMAX devices to customers. Although Clear will still activate existing equipment, potential new customers are being marketed broadband plans on the Sprint network instead.

Former Clear dealers have received word Sprint plans to eventually decommission its acquired WiMAX network as early as 2014, most likely by gradually converting portions of the 2.5GHz spectrum Clear’s WiMAX service now uses in favor of Sprint’s 4G LTE service in urban and high congestion areas. Clearwire itself was in the process of adopting a variant of 4G LTE technology that would gradually replace the outdated WiMAX standard when Sprint acquired the company.

Although Sprint runs its own 3G network, it partnered with Clearwire to provide 4G WiMAX for Sprint customers. In 2011, Sprint announced it would stop selling devices with built-in support for WiMAX and announced it would launch its own 4G LTE network. Sprint will adopt the same version of LTE other North American carriers are using: FD-LTE, or Frequency Division LTE, which requires one transmit channel and one receive channel. But it will also support and continue Clearwire’s upgrade to TD-LTE, or Time Division LTE, a slightly different standard that supports receiving and transmitting signals on a single frequency at slightly different time intervals, providing enhanced spectrum efficiency. At least 5,500 towers should be active with TD-LTE service by the end of this year. End users will care only to the extent their devices support one or both standards.

Sprint’s 4G LTE rollout will depend primarily on higher frequency spectrum that is disadvantageous indoors and over extended distances. Sprint’s competitors AT&T and Verizon Wireless primarily depend on lower 700MHz frequencies that penetrate buildings better and can serve a larger coverage area. But a combination of Sprint and Clearwire’s spectrum assets give Sprint the most wireless spectrum of any U.S. carrier, which means potentially faster speeds and more capacity.

• 1900MHz: Sprint’s primary 4G FD-LTE service is now available in 151 cities on more than 20,000 cell towers;
• 2500MHz: Now used by Clear’s legacy WiMAX network, will see a transition towards Sprint’s TD-LTE service which will be targeted to urban and high congestion areas from “small cell” sites;
• 800MHz: The former home of now-shuttered Nextel, Sprint will eventually launch FD-LTE service on this band which will offer better indoor and marginal area reception.

Customers can expect devices that support both FD-LTE and TD-LTE in 2014.
