We're experiencing very poor quality with You Tube, and it appears we're subject to a bad entry within a geolocation database somewhere.
I'm not sure about Youtube, but Google seems to do some some clever but annoying things with correlating requests going through a recursive nameserver with the location of those browsers. If a bunch of browsers in Atlanta use a recursive nameserver in Los Angeles, Google after a while seems to start offering that nameserver Google server IPs close to Atlanta to give back to its clients. This internet draft might be part of a related work: http://tools.ietf.org/html/draft-vandergaast-edns-client-subnet-00
When we attempt to view videos, the contact comes back to us from IPs like:
I ran into this problem while running a Tor exit node (which seems to terribly screw with this mechanism) and played with it for a while. I found my nameserver being offered Google server IPs all over the globe; one week it would be London, the next week Germany, then New York, etc. My problem was first solved by changing my browser to use recursive nameservers in a different /24 (changing the last octet didn't seem to help) and later by changing Tor itself to use Google's own 8.8.8.8 nameservers, which caused the problem to go away for other clients of my nameserver. Try using nameservers on a different /24 and see if the problem goes away. -- Aaron
