I tried the IP address, copied from John's post, and received this error from HostGator, whoever that might be:
ERROR 404 - PAGE NOT FOUND

I then tried using nslookup, and it gave me the same IP address, which, typed in manually, took me right back to HostGator.
The good news is that therailwire.net came back up for me sometime Monday night, while I was at work, so there weren't any lingering issues here.
