Does anyone have such an index for ISP's in respect to Youtube.com? Idk whether its a routing issue or a bandwidth cap issue but with ATT Uverse youtube is constantly buffer with the video quality set to 720p. Regular speed tests show reliable 12Mb/3Mb bandwidth which should be well enough to stream a 720p video.

I can almost never watch a Youtube video in the evening, even if all other bandwidth tests put me in the tens of megabits. Thought I was the only one.

Perhaps this same issue is happening to you: http://mitchribar.com/2013/02/time-warner-cable-sucks-for-youtube-twitchtv/ http://mitchribar.com/2013/02/time-warner-cable-sucks-for-yo...

U-Verse subscriber here. I have 25Mbps down and I'm glad someone else is noticing this. I first noticed it early of Summer 2012 that 1080p videos were (literally) unplayable; as in no matter how long you waited the video would never start. 720p videos will buffer every 15-30 seconds. This happens no matter what other bandwidth is being used by other applications or devices. I've actually shut down everything in my house and used the desktop on cat5 to see if it was wireless issues or anything, but the entire rest of the web is snappy and responsive except for HD YouTube. Thanks AT&T-- the two hundred and forty goddamned dollars a month I'm paying you should defray the cost of the configuration of your service to flirt with the very line of net neutrality. Dear god please Google Fiber come to Madison.

  I see the same thing on Comcast sometimes, I think it's probably just something wrong with Youtube's routing.

  I gave up on U-Verse, it would go down so often. Switched to comcast and not had any problems with netflix or youtube.

  I have the same issue, but haven't had the time to fully investigate it yet. Other services have excellent download speed, typically about 3 megabytes per second download of say movies purchased through iTunes. But for some reason 1080p YouTube videos will never load. The only thing that could be causing this is if: 1) YouTube's servers can't push the 1080p video out fast enough. (Very doubtful) 2) U Verse hasn't invested in a capable enough link to YouTube's servers. (Possible, but even a 240p video loads faster than a 1080p video. If it was purely a connection issue then 240p and 1080p videos should load at the same slow speed.) 3) They are purposefully throttling HD YouTube videos to ensure that more bandwidth is available for other things. (I'd say this is most likely.) Either way some sort of unprofessional and/or shady thing is happening with U Verse and HD YouTube videos.

  I have 75Mbps down with a fiber optic provider in my area and Youtube is constantly buffering at any HD resolution. I'm pretty sure it's Youtube and not our ISPs.

  I had a similar problem when living in a college dorm; Youtube was suspiciously slower than the rest of the internet. A workaround is to use a ipv6 tunnel. Youtube was literally 5 times faster when my tunnel from SixXs was active.

Back when I was with AT&T, proxying my traffic (over SSH, even) killed all buffer issues I had with Youtube. It's either bad routing or deliberate traffic shaping, and given my experience with AT&T I'm leaning towards the latter.

youtube appears to be doing QOS throttling on some of their named fe's you need to pick one that isn't in your usual path if you're having issues. edit: It appears that the 173.194.55.0/24 and the 206.111.0.0/16 range belongs to Google. Someone revealed that YouTube video requests were utilizing intentional bandwidth throttling that is actually built into their (YouTube) system. Once these ranges are blocked, YouTube's player logic will fall back to Google's datacenters and stream at beautiful speeds.

  Wow, that worked incredibly well; thanks for the tip! 1080p videos load extremely quickly now.

    How did you block those ranges?
    - crynix 14y ago
      If you're on a Mac, it's: sudo ipfw add reject src-ip 173.194.55.0/24 in sudo ipfw add reject src-ip 206.111.0.0/16 in

I am in Europe on a 50/5 Mbit line and youtube is just slow and always buffers if i try to watch something HD in the evening. Speedtests give me 40-50Mbit constantly so it has to be a Youtube issue... very annoying :/
