The FCC Says ISPs Aren't Hitting Advertised Speeds

MojoKid writes "The Federal Communications Commission has released the results of a year-long scientific study it conducted with regard to the upload and download speeds of thirteen American Internet service providers. Most of the ISPs hit 90 percent of their advertised upload speeds. Of the 13 providers tested, only four (or less than a third) averaged at or even above their advertised download speeds (Charter, Comcast, Cox, and Verizon Fiber). The tests were performed by a private firm that has run similar tests in the U.K. It measured performance at 6,800 'representative homes' nationally in March."

  2. Sync vs Useful rates by DeHackEd · · Score: 2

    I know DSL, being an ATM-based technology and often subjected to PPPoE overhead, will score lower than rated. I have a 5 megabit connection but that's the sync rate. You can realistically expect to lose 9-10% just from the above overheads. That rather fits with the graphs I'm seeing.

    I've seen some ISPs compensate by setting the sync rate above the advertised rate but most don't.

      Yes, DSL tends to take a hit from various types of overhead. It's been a while since I dealt with it on a daily basis but I believe that a regular g.dmt connection (8/0.8 Mbps) loses around 15% from overhead when using Ethernet over ATM and TCP. So you'll never see more than 5.9 Mbps or so downstream with TCP...

    Geeze... going back in time... a 1.5 Mbit T1 connection, while actually a continuous 1.5 Mbit connection, never quite delivered that much speed when it was hooked to "the internet" and expected to move TCP/IP traffic. Same for 10 Mbit Ethernet (and that was never a true bidirectional 10 Mbits to begin with).

  8. Re:Wait by ByOhTek · · Score: 2

    Aye, but there's also something this doesn't cover - region. Many of these companies perform differently if you use their service in different cities.

    Where I live, you can regularly expect AT&T DSL to give you about +10% of advertised speed, and we have Wide Open West, which is good (but not listed there). The Insight and Time Warner list there probably overestimate the quality of service here where I live. Actually, since Insight (at least here) uses the TimeWarner infrastructure, it doesn't surprise me at all that they show so similar.

    However, if we conversely go to a friend in another city, her Time Warner acually does meet advertised peak speed, and does so fairly regularly, but equally regularly goes down to DSL speeds.

    The charts that are listed on the TFA are useless except on a per-city basis.

    I have an "Up To 12 Mb" connection through my local cable company. I get exactly that. Somewhere between nothing and 12 Mb. I certainly never get more than that. But given that they advertise it as a "you might get as much as X bandwidth", I don't see how you can say they aren't giving me what they promised.

    1. Re:I get exactly whats advertised. by grimmjeeper · · Score: 2

      I see your point. There should be some differentiation between a 5 and 1.5 mbps connection. And if there isn't, then you might have grounds for a suit.

      However, one of the reasons ISPs put in the "up to" clause in their speed rating is that they are not in 100% control of your entire internet experience. They do supply the connection to your house and then on to "the internet". Once your connection goes out of their zone of influence, they have no control over it. Your traffic can be slowed through choke points completely out of the control of your ISP, not to mention trying to download from an overloaded server. (Slashdot effect anyone?) Even if the third party server is on their own network, it can still be overloaded. The connection to the server can be just fine but if the server is slow, there's nothing they can do about it. You can have a 1.5mbps connection or an eleventy gazillion mbps connection but if the server is only dishing out data at 56kbps, that's all you're going to get.

      I'm not trying to defend ISPs but there has to be some reason applied to the standards to which they are held. I don't think expecting them to always meet their "up to" speeds all the time for everyone is a reasonable standard. Though meeting 80% of advertised speed for the network is probably not a terrible starting point for the standard. And that should include the ISP's upstream connection. If they have oversold their upstream connection and it is the source of the restriction, they should be held to task for removing that bottleneck. But the one gaping hole in the standard is that no ISP can guarantee that any one particular connection to any one particular server will result in the desired speed. They just can't provide that kind of guarantee because it's ultimately something they just don't have control over.

  11. Burst-Based shaping skews results by ZeroNullVoid · · Score: 3, Insightful

    Most of the providers who hit their advertised speeds implement a burst-based traffic shaping.

    For example, Comcast does full or over-full speed for first 10mb down and 5mb up.

    It's nice that speedtest sites like speedtest.net show a graph of how speed changes, but their test sizes are still far to small and should exclude any detected burst speeds.

    The only good way to test this is to actually transfer files and exclude the bursts.

    Another thing that SHOULD be tested is the speed difference with single threaded transfers and segmented/multi-threaded transfers for both same continent and cross-seas.

    Internet speed is relative and that is part of the problem.

    When I had issues with my Comcast cable internet connection, it was taking me about 5 minutes to load Google's home page, 10 minutes for the nytimes.com home page. Slashdot took about 7 minutes. I went to three different independent speed test sites, which each confirmed I was getting less than 5% of the bandwidth Comcast advertised. I called them up and they directed me to a flash animation that looked like an analog gauge of a car speeding up onto the freeway, overshooting the advertised bandwidth, wavering a bit to make it look like it was actually measuring something and leveling off at exactly the advertised bandwidth. I reloaded it a couple times, and each time it was the exact same animation. The rep then said, "can you read me what it says on the dial? Looks like your connection is working just fine. The sites you are trying to visit must not have enough bandwidth to handle the connection." I asked if she'd ever heard of a little company named Google, and she said they must be having network trouble on their end.

  17. I'm in that FCC study, and here's what happened. by quixote9 · · Score: 5, Interesting

    Before participation: Time Warner/Roadrunner here in Southern California gave me less than a tenth of advertised speeds. Officially 7mbits down, 1mb up, the actual service was more like 400kbits. Up to 800kb, sometimes even over a whole megabite early in the morning. (Exciting!) After the initial burst, which hit over a megabit down fairly often, there were times when it slowed all the way to single digits in KB.

    Under the Sam Knows program, the FCC lets the ISPs know which subscribers are part of the test. (Bit of a problem right there, I'd say.) A few days before we had the government router hooked up, no doubt when Time Warner got word of our new "status," our speeds suddenly shot up into the advertised range. I nearly swooned the first time I saw a download go by at over a megabyte. And, interestingly enough, they've stayed there. It wasn't just some random thing. We don't usually get 7mb, but 5-6mb is the norm now.

    So the info that ISPs aren't delivering stated speeds even in the FCC study is interesting, given that they seem to be jimmying the results for all they're worth.

    (Speed tests before the FCC program would show us getting multi-megabits that we never saw in real life. Two things there: burst-shaping, no doubt, and I've heard that ISPs have ways of recognizing speed test traffic and giving it bandwidth.)

  19. U.S. Getting Screwed by StormReaver · · Score: 2

    I recently watched a PBS special about broadband, which indicated the UK's system is setup so that most households have a choice of multiple broadband providers, where high speed starts in at least 2-digit megabits per second, and the monthly cost is almost trivially low (I forgot the actual costs that were mentioned).

    Although the lines are owned primarily by an oligopoly of companies (AT&T, Verizon, and British Telecom were the three mentioned), they are required by law to lease the lines to competitors. Not only that, but Verizon, AT&T, and BT all wholeheartedly endorse the the concept of being required to lease their lines to competitors. Spokespeople for those companies all said that the required competition kept them working to improve their respective services.

    The special also said that the companies are investing in massive new outlays of fiber optics across the country so that even very remote and sparsely populated outlying areas get fast Internet.

    Now shift to the U.S., where Verizon and AT&T are fighting tooth and nail against regulations that would provide the same level of service and network expansion going on in the UK, and where 3mb DSL is considered high speed (by AT&T).

    It just drove home how royally screwed we are in the U.S.
