AGIS will act swiftly to get this fixed, they also have serious customers. It would make a very bad dent in their reputation to be locked out of a continent. 2. Your host will receive "host unreachable" and not keep the TCP session block around. >What should be done is to have our transit operators stop announcing >our networks to AGIS/IEMMC.

Well, then somebody else in America will take action, because we'll just move over and block them next if they don't act. Remember, making their IP numbers useless is the hardest way we can hit them, get new IP# are not easy (the fact that you're on this mail-list means that you know that :-) For this to work, we need to get europe to work as a block, if the bigger party blocks the smaller, the smaller has a problem. If the smaller party blocks the bigger, nobody cares. -- Poul-Henning Kamp FreeBSD coreteam member phk at FreeBSD.ORG "Real hackers run -current on their laptop."
