To minimise this, I'm suggesting a handful of servers that have been *mostly* together all evening. I make no guarantees. Hopefully, if we're on a few servers, this will keep the splits low, and a we won't help overload a single server.
It seems that it's mainly hubs and the servers connected to them that are being split off, so these seem fairly safeish. Caveat emptor, as always...
And if all that fails, I'll have my IRC server running.
