Frustrated YouTube fans have complained all year about degraded performance, videos that don’t play, and endless rebuffering of online videos. Now a third-party has placed the blame for this on YouTube’s owner Google, which is allegedly running server farms overloaded with YouTube video traffic.

Sandvine’s Dan Deeth argues that super fast broadband speed and the providers that deliver it are not always the best indicators of subscribers’ ‘Internet quality of experience.’ More important, Deeth writes, is how well an Internet-delivered application or content works for consumers.

Broadband users typically blame their Internet Service Provider when a website refuses to load or an online video staggers from one “buffering” pause to the next. But the bottleneck is sometimes beyond the control of your provider and may even reside at the content distribution network sending you the streamed video.

Among the most frustrating online video experiences this year comes from YouTube, owned by Google. Users complain videos never start, timeout, constantly buffer, or downshift to lower video quality.

“The enormous increase in ads all seem to play fine, but there are dozens of times the video itself never begins at all or quickly times-out to rebuffer,” said James Bellwar.

Hyun Soo Park, a YouTube contributor that earns side income from sharing ad revenue says YouTube is getting hopeless.

“My fans are giving up and are occasionally even angry at me because they think I am responsible for the ads that play fine and the videos that do not,” said Hyun.

Blame Google, says Deeth:

We can rule out ISPs being the root cause of YouTube’s quality issue. Instead, we can conclude that the root cause of the degradation in quality is likely occurring because of an oversubscription in the Google server farm (where YouTube is hosted) which makes YouTube unable to meet high lunch time and evening video demand. This oversubscription would result from a commercial decision by YouTube to regarding how much capital they wanted to invest in server capacity to maintain quality.

For those interested in examining further, YouTube has a ‘my speed benchmark’ that seeks to measure ‘maximum demand’. You can use these benchmark tools to not only view your historical YouTube performance, but also measure in real-time the performance of a video you are viewing.

While consumers are caught in the middle of the finger-pointing, there is a solution to keep YouTube videos from endlessly buffering. PC World offers a way to force YouTube to send the entire video instead of the current system that only pre-buffers small segments of content.

Richard Miller from the Capitol Fax blog spent the weekend at the Illinois State Fair and might as well have left his AT&T cell phone at home, because the wireless giant’s network collapsed with an overload of traffic.

“Both days, after 5 o’clock in the afternoon, AT&T’s mobile phone service wouldn’t work,” Miller writes. “Calls in or out were sporadic at best, and texts took numerous attempts to work, if ever. Internet? Fugetaboutit. And when the nightly concert started, everything completely shut down. No calls, no texts, no nothing.”

How to improve AT&T service? Remove the rules that require them to provide it.

Miller reported friends attending the fair with him had no difficulties using Verizon Wireless, Sprint, or T-Mobile, so Miller concludes the problems were AT&T’s to own.

“There’s no excuse for the giant corporation’s lousy service,” said Miller.

Attendees with missing children or needing to make emergency calls were plain out of luck. Pay phones are long gone. The only alternative was finding someone with a phone not served by AT&T.

“[People] pay good money for the service and they have a right to expect that they can use their expensive communications devices at large annual events, where people get separated all the time,” said Miller.

Ironically, the Illinois Farm Bureau (IFB) received at least $20,000 from AT&T in 2012 and is for wholesale deregulation of AT&T. The Illinois Partnership for the New Economy & Jobs, a front group for AT&T Illinois, noted that the farm bureau is all for “updating” Illinois state laws that take the hook off AT&T’s responsibility to serve every resident in the state. A preview of what that looks like was experienced by Miller and others at the state fairgrounds.

TracFone customers signed up for NET10 Wireless prepaid service are getting word in e-mail the 1.5GB monthly data cap on AT&T-based SIM cards introduced in March has been removed and unlimited data has returned.

AT&T resells prepaid access to its 3G GSM network on gradually improving terms as AT&T’s postpaid, on-contract customers continue to abandon 3G in favor of AT&T’s 4G services. As 3G traffic loads diminish, AT&T is seeking to maximize return on its older network. Bringing back unlimited data service is expected to prove an attractive offering in the budget-minded prepaid marketplace.

TracFone acts as a reseller of all four major carriers’ networks under different brands. Geography and the specific phone model chosen usually determines on which network the service will operate. Only customers with AT&T SIM cards in their phones (the first line of the SIM card ID number will end in “SIMC4”) qualify for the unlimited data offer, although tethering is prohibited, according to an e-mail being sent to registered customers.

TracFone enacted a 1.5GB monthly usage cap for NET10 Wireless users back in March. But the cap never applied to TracFone’s Straight Talk customers. Straight Talk still offers unlimited data, but says streaming is not permitted.

Along with the return of unlimited data, TracFone has discontinued its NET10 Wireless usage measurement portal, which informed customers about their monthly data usage.

TracFone operates several prepaid calling plans under the brands TracFone, NET10 Wireless, Safelink Wireless, Straight Talk, Telcel América, and SIMPLE Mobile. TracFone is owned and operated by Mexico-based América Móvil.

Just as in the United States, the promises made by satellite broadband providers are turning out to be too good to be true.

In Great Britain, commercial broadband providers have argued satellite Internet access is a better solution for rural residents because wiring out-of-the-way places is “too uneconomical.”

Despite promises of 20Mbps service from satellite operators, customers report actual speeds are well below 1Mbps at the times they actually want to use the Internet. Unlimited access is also increasingly a thing of the past, replaced with usage caps of 50-60GB, with unlimited usage from 11pm-7am.

Providers deny any serious problems, pointing to speed test tools developed and released by the ISPs showing speeds are theoretically great. But browsing the public Internet suggests otherwise.

Avonline customers have a very active ongoing discussion complaining that £65 satellite broadband should work better:

For past three weeks, the service takes a dive in the evening, I thought this started about 7pm but having tried it earlier, it’s more like 5pm and today about 4pm. Speed tests provided by Avonline suggest I am getting 20/5Mbps but all other tests suggest between 1 and 2Mbps download and ?? upload. Often their own speed test stalls on the upload altogether or eventually returns a result of 0.1Mbps or similar.

As a family, we come home from work and school and want to watch things online at a time to suit us as terrestrial TV is a bit dire. The service is unavailable at this key time and remains down until 1 or 2 am.

Unlimited customers paying £75 per month have been told they are “abusing” the service and that it has effectively run out of capacity and is oversold.

“Unfortunately we cannot do much about the bandwidth on the shared network during peak hours,” came one response from Tooway, another satellite ISP that recently disclosed it will only sell unlimited service to 20,000 customers and wants assurances customers are using their accounts for private, family, and personal use only before the overnight usage caps come off.

*-Only applies at 3am.

But even then, some customers say pervasive speed throttling accomplishes the same thing as a strict cap – it keeps customers away from the service. One Tooway customer shares his dissatisfaction:

The Fair Use policy posted by ToowayUK has only just been introduced. Prior to this there was just boilerplate language that boiled down to “we can do anything at any time” (not that different from the FUP language of any other ISP).

Of course what is really a joke here is that the “unlimited” service actually has a 60GB cap – the traffic management policy works just the same way if we go beyond 60GB as when a capped customer goes beyond their cap.

ThinkBroadband notes satellite ISPs may also have insufficient capacity back on earth, but later reports show satellite bandwidth capacity is also a growing issue:

The KA satellites carry many transponders, but these are usually spread out to cover the whole of Europe meaning that for any particular satellite there may only be 3 or 4 transponder beams for the whole UK, and as a transponder has a throughput limit of 475Mbps this could prove a bottleneck. Oddly the fact that the speed probe tests gave good results, suggests the issue may not be satellite capacity but rather the purchased amount of capacity from the ground station to the Internet at large.

Netflix kicks off the summer rating the streaming video performance of some of America’s largest ISPs, and the results deliver only a few surprises.

Google Fiber is the runaway leader, but Verizon FiOS — also a fiber-based network — is lagging behind several cable operators, notably Charter Cable and Suddenlink.

In mid-June, GigaOM reported Verizon was engaged in a battle with Cogent — a bandwidth provider Netflix depends on to help it reach Verizon customers.

Cogent promptly blamed Verizon for the slowdown:

Cogent and Verizon peer to each other at about ten locations and they exchange traffic through several ports. These ports typically send and receive data at speeds of around 10 gigabit per second. When the ports start to fill up (usually at 50 percent of their capacity), the internet companies add more ports. In this case, through, Verizon is allowing the ports that connect to Cogent to get crammed. ”They are allowing the peer connections to degrade,” said Dave Schaeffer, chief executive officer of Cogent said in an interview. “Today some of the ports are at 100 percent capacity.”

“Think of it as the on-ramp to the freeway being log-jammed,” Schaeffer said. And that means your Netflix content, especially content sent by Netflix’s content delivery network, slows down, and you get pixelated pictures and buffering.

Verizon just as quickly shot back at GigaOm and Cogent:

Cogent is not compliant with one of the basic and long-standing requirements for most settlement-free peering arrangements: that traffic between the providers be roughly in balance. When the traffic loads are not symmetric, the provider with the heavier load typically pays the other for transit (see our ex parte filing [PDF] from the 2010 Comcast/Level 3 spat for more info on peering and transit agreements). This isn’t a story about Netflix, or about Verizon “letting” anybody’s traffic deteriorate. This is a fairly boring story about a bandwidth provider that is unhappy that they are out of balance and will have to make alternative arrangements for capacity enhancements, just like any other interconnecting ISP.

Customers don’t care. They just know their efforts to watch Arrested Development are being stymied, and Netflix’s June ISP results illustrate the degraded performance customers are getting.

Cablevision, the top performing cable operator, can likely thank its recent investments in network upgrades for improved performance, not its participation in Netflix’s OpenConnect Content Delivery Network, designed to improve streaming performance for participating ISPs. Cablevision is a member, but so are Frontier Communications (#14) and Clearwire (#17 and dead last).

OpenConnect couldn’t help Frontier DSL or Clearwire wireless customers achieve good results — the technology in use and the upstream connections both companies maintain with the Internet backbone mattered much more.

In general, fiber performs best when everyone is getting along, cable comes in second, DSL third, and wireless last.

But if you want the best performance possible, and Google Fiber is not in your neighborhood, your best bet is to move to Sweden, where the top-six providers all outperformed every American cable, DSL, and wireless provider. In Finland, the top-four beat everyone but Google Fiber. The nine best-rated ISPs in Denmark also outclassed their American counterparts, while in Norway a half-dozen providers did better.

But many ISPs in the United States can still be proud: the top eight beat Mexico. Mediacom, AT&T U-verse & DSL, Bright House, CenturyLink, Windstream, Frontier, Verizon DSL and Clearwire have some work to do… if they want to keep up with those speed mavens in Guadalajara.
