I think that it was Curt Sampson that was thinking about putting together a
list of PMTU broken sites.  (PMTU on, but ICMP turned off). Anyway, I just
thought I'd post this URL for the other "problem".

Subject: ECN and ISOC: request for help...

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:

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
