Unexpected Downtime

Update (Wed 1:10am EDT): We are back up and running now.  Approximately 4 hours ago, our database servers became unresponsive.  We were able to restore the database without having to revert to a backup (which continually maintains a snapshot no more than 4 hours old).  There was no loss of data during this outage.  We do apologize for the length of downtime, which was more than we expected.  We will be continuing to work tonight, tomorrow, and in the days to come to ensure that this does not happen again.

Original status update (Tue 9:00pm EDT): We are currently working to bring our database server back online.  We apologize for the inconvenience and will keep you updated here.
