Tonight we will be completing the migration efforts from last week. At 9 PM Eastern we will be dismounting the mailbox databases and move them to the new RAID array on the new server. The move is expected to take about 3 hours to complete.

Update 9:30 PM Eastern: We are beginning the database move on Scrooge. Service is expected to be restored by 12:30 AM Eastern.

Update 1:40 AM Eastern: The database move is still in progress. Currently there is no ETA on a restore of service, however service will be restored before the start of business.
