I notice it's partially up now. "
www.gearheadrpg.com" still doesn't work, but "gearhead.chaosforge.org" partially works (it didn't at the start of the crisis). The main problem is that most internal links, including stylesheet links, are absolute and thus go back to the still-broken gearheadrpg.com domain.
WHOIS shows Joseph owns gearheadrpg.com directly, so I guess it's up to him to update the IP address. I tried hacking my DNS to override *.gearheadrpg.com with the IP address of gearhead.chaosforge.org, and that seems to make it work fully for me. (Although I haven't tried posting anything.)
The SEO spammers seem to be gone, for now. That's nice.
