Sorry this has taken so long - I've had to install an OS several times on this box before I got things to where I thought they would work reliably.
Short story: Something in my old server ate itself so that it wouldn't server the 2dPNR website up anymore. It still works for email, although that will be getting migrated soon enough as well.
If anyone has any favorite, cheap Linux backup (and restore!) solutions, I'm listening. In the meanwhile, this page is going to look pretty rough while I get it worked out.
