Happy Y2K to all! Looks as if GTEI has begun filtering ICMP type 0 and 8 (I
hope that's all) through their backbone. I heard that this was because of
DoS threats, but I haven't seen any other commentary on the subject. GTEIs
NOC claims that they have made no changes. From some places I can get
through the network, but others fail. CERFNet and others are clean.
Traceroute works fine everywhere. Has anyone else seen anything similar?
Regards,
Christian
