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.
Yes, which in my case is an indication of the system working properly. Leads me to wonder if the issues I have with Comcast + YouTube are on the Comcast side, the Google side, or are just the nature of the streaming-video beast.
