Indeed, I have seen this behaviour for at least a week. It seems to
somehow be related to geo-located DNS (akamai?) since the timeouts and
RSTs I see in the traffic are from IPv6 akamai servers, not facebook itself.
I tried de-peering from a number of networks to try and isolate it and
it was not transit-specific. I stopped questioning my network when I
saw a thread on Sixxs and tunnelbroker about this very issue.
Hopefully it won't persist as right now as having Facebook
intermittently connect is likely hurting deployment slightly.
