Can't Things Work for one Day?

I don't know what happened. Everything was fine until the weekly jobs ran at four in the morning, then the entire site reverted to "Here's your brand new domain!" Everything is still there, but for some reason the http server is pointing to the default directory. None of the configuration files changed, and I've restarted httpd several times now. I've got a ticket in with lunarpages. It's just one fucking thing after another.
