Kai what if UUnet is running some type of QOS mechanism in their
core network that prevents massive amounts of icmp messages
traveling through? Maybe they are rate-limiting everyone with CAR.
Their infrastructure is interesting they use Cisco, Fore, and Juniper
at least in production. And they claim they run an MPLS network;
maybe this is where icmp traffic is killed..
