I wanted to let everyone know that the transition from Pair networks to Slicehost has been completed, and the domains redirected. As far as I know there was no downtime. I'm somewhat amazed that it all went so well.
The only thing not yet worked out on the public facing side of the transition is the forum's outgoing mail server, which I still need to setup on this server. Until then, the forum won't be able to send out mail, so please don't forget your passwords!
