Mars lander (Re: How to achieve application reliability)

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.
