I can tell you from experience that rebooting the router may not be enough. It has to be reset sometimes in order to refresh the routes.

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.

Yes I get 216.235.254.230 also. That is the first thing I check. I check

firewall settings on the Comcast gateway.

Here is what my traceroute looks like:

$ traceroute blu.org

  1?: [LOCALHOST] pmtu 1500

  1: 10.0.0.1 7.734ms

  1: 10.0.0.1 8.688ms

  2: no reply

What IP Address do you get from "host www.blu.org"?

FWIW, I see 216.235.254.230

And I can reach it (from ATT and from Coresite)
