How can you be so sure the hosts you were hitting with pings and
traceroutes were the same hosts? It's quite possible smoke and mirrors
were in between (smoke: web directors answering the pings... mirrors:
anycast addressing with policy routing).

It's getting pretty wierd to debug IP these days...

sure, i was admittedly making some blind assumptions.  i didn't check
any dns entries.  then again we've all seen a few other "media events"
fall over and die because folks haven't done the server/os/app side
very well.
