I submitted a request for a main domain change, but it appears to have hung. I've done this in the past and its occurred within minutes, this has been sitting for around 12 hours.
I am getting general slowness and 500 errors on regulate.x10hosting.com. When I try to use Cpanel to look at the databases it also hangs, so my guess the problem is with the database.
Many users are reporting the same problem on the forums here: http://x10hosting.com/forums/free-hosting/
