The services for the host on list.org www.list.org mail.list.org strongbadia.list.org 206.131.226.62
[all the same host/machine] Including "list.org" SMTP and "www.list.org" HTTP -- Appear to be affected by a 'faulty router or firewall' of some form, that THROWS AWAY "TCP SYN" packets trying to connect to the machine if the 'ECN bits' (previously 'reserved for future use') are set on the TCP packet. This problem most affects Linux users as the Linux 2.4 / 2.6 enable "ECN" (explicit congestion notification) by-default and do not provide a "fallback mechanism" like some BSD systems do! I.e. such systems will TOTALLY FAIL to connect to such a host. Hosts that do not understand "ECN" are supposed to merely ignore these bits and carry-on-working-as-usual like the vast majority of hosts do! Many distributions disable ECN at boot-time to work around such broken hosts which are decreasingly-common.
