Right after the move, the power supply in one of the new servers died. Unfortunately, the database was also running on this server and I didn't have mirroring set up yet. It required a physical trip to the data center, but we recovered the data and failed over to the second server.
The first server is back up on a borrowed power supply. We have have ordered a replacement, but this shouldn't require additional downtime.
Sorry about this... hopefully you've at least noticed the speed improvements. The site should be snappier now - and we can get back to writing good content.
