yeah.

rizon is designed to be big and to sustain attacks. As a result, when things happen, it splits. Servers can get ddosed out of existence for a while, and the network just splits them off and keeps going.

most irc clients are kinda dumb though. If you're on the wrong side of a split when a server goes down, just like hiroshi said, you'll probably keep the same resolved name and keep trying to connect to that.

names like irc.rizon.net and eu.rizon.net are supposed to be "load balancing" points ... they redirect you somewhere or another. Your best bet if you're noticing repeated failures is to try /server irc.rizon.net or /server eu.rizon.net or whatever again, and get a different name to resolve.

of course that's a problem when those points die.... but that's another story entirely.
