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.

Are people idiots or do they just not possess equipment capable of trashing 92 byte icmp traffic and letting the small amount of normal traffic through unhindered? They are raising freakin' complaints from users who think the Microsoft ICMP tracert command is just the end all, be all and is of course completely WRONG with rate-limiting in effect.
