We've noticed that one of our upstreams (Global Crossing) has introduced ICMP rate limiting 4/5 days ago. This means that any traceroutes/pings through them look awful (up to 60% apparent packet loss). After contacting their NOC, they said that the directive to install the ICMP rate limiting was from the Homeland Security folks and that they would not remove them or change the rate at which they limit in the foreseeable future. What are other transit providers doing about this or is it just GLBX? Cheers, Rich
