ICMP traceroute works over my Cox peer in Florida. Ping to a Cox destination also works.

For those of you with COX or a COX Peer, it seems as though COX has shut off ICMP transiting their networks. I do not have a time yet when this will be fixed.
Has anyone confirmed if this affects all ICMP, or just specific ICMP types (e.g. echoreq/echorep)? If they're blocking all ICMP, someone at Cox needs to be fired immediately. -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
