Ok, so I know the forum is up, but I still can't get to it...

av123forum resolves to 69.64.71.243 which I get no reply from when I try to ping it.
A trace route doesn't really help me...

I've rebooted this PC, my wireless router and my cable modem with no changes. I haven't noticed any problems with any other sites I've tried to go to. I can get to av123.com though

Any ideas?
