I experience a lot better performance on videos loaded from our GGC node
vs. videos loaded from google/youtube. The problem definitly appears to
be on googles side as we peer directly with them and our link is not
saturated. When I watch a movie it might have problems with buffering in
480p while turning it up to 720p might (or might not, seems quite
random) solve it, which makes me think the problem is within Googles
network. I know several other ISPs in Norway that have suffered from the
same issue. The problem stopped occuring from all videos that were
cached after we installed GGC, and now buffering the entire movie
happens within a few seconds regardless of quality (for IPv4 users that is).
I wouldn't "blame" Google if I didn't know of several other ISPs that
had the exact same problem and they all solved it by installing a GGC
node in their network.
Anyway; this is a bit off topic as the main issue is that people with
IPv4-only GGC gets worse performance if they roll out IPv6 as they don't
get to utilize the GGC node.
