"Sorry, but there shouldn't have been any point during this attack when you couldn't hash (apart from the few tens of seconds taken for the rollover). My miners went from BTC Guild to 50BTC to Slush without missing a heartbeat. Now I've manually configured the private server as first in the failover chain (last is solo mining).
You need to make sure you have an effective failover strategy in place."
Can't speak for anyone else, but my miner (BFL Single w/ BGFminer on Ubuntu) refuses to stay connected to any pool besides BTC Guild, that's why I was on it. The only other one that works is BTCDig and that is a really small pool, that I can't seem to stay connected to today either.
