Basic Internet Connectivity And Modem Help

[mmathis]

Since Saturday afternoon, I am being blocked from access to certain domains.  Critically, I am also not able to receive emails from 2 of my own hosted domains.  After exhausting all local trouble spots, then going to my web host, it seems the issue is internal to comcast networks.  My traceroute results show a Level3 router in Chicago is blocking access to the effected domains.  It seems Comcast and Level3 do not play well as I've found instances of this same problem in these forums, allbeit in different cities.

Below is the culprit in my attempt to access aspwebhosting.com site.

10    32 ms    33 ms    33 ms  ae-22-52.car2.Chicago1.Level3.net [4.69.138.36]

11     *        *        *     Request timed out.

Does anyone know a work around while I wait the 24-72 hours comcast quotes as a response time?

Works OK for me. Traceroute using SamSpade.exe.

Can you post a failing Trace Route?

[Barmar]

What happens if you go to your web host and try doing a traceroute to your home IP?

BTW, I'm seeing the same behavior as the OP:

 It's probably dependent on the Comcast IP block you're in.
