There are a lot of threads popping up reporting the same problem. I'm sure XHosting is working on it, and we probably just need to give them a few to get it fixed.
I also can not connect to the server with my Frontpage (already reinstalled but no luck) and that usually means a problem with XHosting, but like I said with so many threads popping up, I'm sure they are on it. Bet things will be fixed whithin the hour.
