I got on for a little while, before that it was going to a generic 'search bowling' page that seems to be for domain names not in use. After it worked for awhile then it returned to going to the generic search bowling page again.
It looks like there are 2 DNS A records for it, one being 69.64.155.21 and the second being 209.51.196.186. They round robin from one to the other for each DNS lookup done, which usually means two A records have been entered into the DNS record for the same domain name.
So I'm guessing that's the issue causing the page to not work sometimes, for some people. Probably depends on if your system has cached the good or bad IP address, and have to wait for it to time out before it either breaks or works again.
