We've been suffering from high temps here in Wenatchee.  If you didn't see the news, we've had temperatures as high as 113F (45C), as well as a large fire that came into town and burned 28 homes and some large buildings, forcing people to evacuate from their homes (including me).  The fires did not threaten the mine, however they produced a lot of ash, which clogs our filters.
We are cleaned up now, but temps have been consistently over 100F for the last two weeks.  This has caused significant reductions in hashpower.

Add to that the recent transaction spam attack caused pool server outages (Bitcoind crashing) and forced an emergency switch to Eligius.  I'm going to leave everything pointed at Eligius for the time, which cause payouts to get inconsistent until I can revise the system.
