Are you using IPv6 or an HE tunnel? |

Looks like it's a routing problem in Comcast's network. Do you agree? |

Gotta love those tunnels Others have reported a problems previously. » www.gossamer-threads.com ··· v6/34197All said, it's probably not that much help to you. Maybe someone at Comcast is willing to reach out here. Bill's scamper results in the v6 ops list seem like there is a pretty clear issue with the load balancer. |

Maybe someone from Comcast will see this tomorrow during business hours and get it fixed. |

Folks, We're aware that there is currently an ACL issue blocking ICMP at the last hop. The site is reachable via normal means, but if you are using a tunnel that is constricting your MTU, you will not be able to reach it as PMTUD will fail. We are working on a fix. |
