Well, the initial onslaught has been quieted. It wasn't a pretty transition as far as transitions go, but it could have been much worse.

We are now running a beefy set of four servers (thanks in large part to Sifter contributions) consisting of a load balancer front-end, two web servers, and a DB server.

There were several challenges we had to overcome to get this all worked out properly, but everything is now running at full speed and our load is lower on both web servers than it's been for a long, long time.

There may still be an issue here or there, but everything seems to be working surprisingly well at the moment. (Yay!) Knock on wood.
