Servers are looking pretty stable again.  This whole issue at least allowed the removal of the pool from the web server, which means a pool issue won't bring the website crashing down as it has in the past.  The sync code between servers also received an update after taking down US West, NL1, and NL2, far less aggressive sync attempts (meaning one server having connection issues won't take down another server with it).  The downside is it means that rounds may extend a few seconds past their actual solve time (up to a minute).  The upside is that if one round is extended due to a sync issue, the following round will be that much shorter.

The new server hardware will hopefully be online around July 11.  It's IMPOSSIBLE to effectively stress test this kind of machine to replicate the real world conditions, but the underlying software configuration has been tested with the help of the IRC chatroom.  Failover when a sub-pool crashes takes about 4-6 seconds to kick in, meaning you can point your miners at one IP and it will automatically put them at an internal pool.  There will still be an EU alternate set of servers, so if a connection issue occurs between you and the US pool, there are still fallbacks on different ISPs.
