My guess is that there's something wrong with your or DigitalNation's network config because I was able to reach your server via telnet:
roberto@brasileiro:~$ telnet 216.167.114.244 80
Trying 216.167.114.244...

But when I tried accessing davecubed.com (to which that IP resolves) I got a "We registered our domain with VERIO" page. Trying to access the IP returned a "connection refused by linux1162.dn.net" error, which could indicate DNS problems.
