Mars lander (Re: How to achieve application reliability)

Yes, it was very impressive. I was hoping they would be successfull, because
in a few weeks the next event will also require some interesting web site
hosting. If it had worked, then the people who follow could just copy it.
Even without a feed to push, the sites were unresponsive for parts of the

I'm very concerned we still haven't proven we know how to handle big event
sites on the Internet.

Not to harsh on the design at all, but is round trip time (the F5 solution)
the best way to calculate which distributed hosting / caching site a client
connection should go to? Variance in rtt from one trace to another, or
variance in hop count from one trace to another, could lead to inconsistent
balancing results as the client/server connection is going to be stuck in
some kind of quasi-flow cache and additional requests forwarded from the
client to the same server.

Is it safer to use a bgp AS_PATH or MED over pure rtt? (granted, routes can
flap and cause the same effect, but is it as much of a problem) Is anyone
willing to share experiences with one or the other?
