Good. I swear youtube is throttled by Time Warner Cable for me. I stream Netflix, Hulu, etc and never have problems with them. I can confirm that I'm getting my speeds of 20MBit/s down, and yet almost every video on YouTube buffers. If I use youtube-dl to download the video, I can confirm that my actual connection speed is somewhere around 60KB/s. If I then use youtube-dl on my VPS with the same video, I get somewher…

Are you by any chance using non-TWC DNS servers? I had this same frustrating problem on Comcast, and it turned out that their CDN works by using DNS to direct you to local servers; by using the Google 8.8.8.8 etc I wasn't getting that. Even still, though, I run into certain Youtube videos that absolutely refuse to ever fully load -- it's always non-popular ones, and it's like they cache miss and just never get surfac…

Have had the same experience on Comcast.

They probably do it, but Google is at fault, too. Their new DASH thing has made the experience so much poorer. They never should've done it to begin with, and I don't think whatever savings in bandwidth they might have from it are worth the compromise.

Youtube was perfect before, because it allowed you to cache videos, and go back on the videos whenever you wanted, with no need for reloading or whatever. DASH made it a much worse experience, at it only caches like a few seconds at most in front of the streaming, and it won't even allow you to go back in the video without reloading it again.

I wonder if proxying just those sites through a $5/month Digital Ocean server would work...

Curious. For me the 30-240 seconds long ads YouTube shows are always 1080p (or at very least high quality) and never choppy, yet streaming YouTube content videos at the same resolution often results in terrible buffering issues. Are the crappy ISP (ComCast) cahce servers only caching the non-ad videos? Does YouTube serve these through an AdSense / non-YouTube source that bypasses the cache? There are times it seems the only part of YouTube that works are the ads.

The ads are cached because the same ones are shown to so many people. Most videos are served to any particular neighborhood much less frequently than ads, and so are usually not in the edge cache.

I think Comcast is doing the same thing here in Colorado. Lately, I've been seeing quality drop in videos where it shouldn't. Running speed tests or downloading from newsgroups I'm hitting 60mbps.

Ditto here re Comcast, but in Mountain View. I am a stone throw away from YouTube HQ and still get bad performance. Tried the 8.8.8.8 DNS and not much different. Comcast is definitely squeezing the pipes!

Worked for me when I had streaming problems with AT&T, but AWS micro was the cheapest at the time.

I've noticed a trick when watching long HD youtube videos that I need to pause and re-wind several times. If I'm signed in to my web browser the video quality is demoted to lower quality after a while of watching, pausing and re-winding. To avoid this degradation of quality, I use a browser in incognito mode, and the quality stays HD. Does anyone who why this occurs?
