[Discuss] Problem accessing blu.org

[derek at ihtfp.com (Derek Atkins)]

Did you try rebooting your router?
The fact that it's not even getting *PAST* your router is a little
suspicious.  One would think it would at least get one hop out.
Granted, there COULD be a routing/BGP issue between Comcast and Level3. 
It wouldn't be the first time.  But again, one would expect that at least
one hop out.
