I had a brilliant idea, but it fell apart:
From poking around, it's possible that the DreamHost account that hosted this site expired. I tried doing a nslookup here for the domain, but it returns nothing.
I was hoping to suggest that the user(s) manually add the IP address to their local hosts file, then point the browser to the site, thus bypassing the nameserver. If DreamHost is still hosting the site, then the Apache server would still respond to a query to that domain name.
This didn't work, either:
garth:~> curl www.outlawstoughcrowd.com
curl: (6) Couldn't resolve host 'www.outlawstoughcrowd.com'
This isn't looking good.
