In its great wisdom, the IETF has divised a system to control congestion over the Internet called ECN [RFC3168], unfortunately there are still some routers out there which are "Explicit Congestion Notification" (ECN) broken: http://urchin.earth.li/cgi-bin/ecn.pl One of this router leads to the ISOC web site. what is funny is to see the above RFC is copyright ISOC. Could someone located in the Washington DC area please contact the ISOC people and help them to be RFC compliant... I have highlighted to ISOC the problem, they are aware, but understaffed and this is a little bit tricky, but it should be a piece of cake for the IETF members.
