Just went into failover again. I can always tell because the fan speeds change on my miners for about 30 seconds or so.
I really need to rethink how I'm doing failover. I have it going to Slush's when it fails over, and these short failovers are apparently too short to actually gain anything on Slush. Apparently I get awarded a nice fat 0.
I use BTCGuild as my failover on PPS bc then once Eligius is back up I can do a manual payout and get all the coins.
