I suspect the DNS entries on the servers themselves may look fine from inside facebook, leading to a slower diagnostic and repair, as it's only from the outside world the missing routing entries in the global table make the problem so painfully visible. Having the DNS team frantically checking their servers may slow the resolution down, if it is indeed a BGP failure rather than a DNS server failure situation, as it seems to appear at the moment. ^_^; Matt
