Routers aren't forced to support ECN (although it's in their interest) but they aren't allowed to drop ECN-flagged TCP packets. If you can't access a site, *they* need to fix their buggy router to be ECN-tolerant. If they don't do so, they're violating RFC 793. http://www.ietf.org/rfc/rfc793.txt?number=793 -- Eric VAN BUGGENHAUT "Oh My God! They killed init!
