Downtime 1/6/13 at 3PM Pacific

I'm taking the database down at 3pm Pacific time today, Wednesday January 6th, 2013.  That means all websites will be down during the switchover.  We should be back up by 4pm Pacific.  

UPDATE 3:32PM: The maintenance went well, so we're back up!  Hopefully there'll even be some performance improvements come out of it!
