Hi Joseph,

I am also using a Cox cable modem, but I have no problems reaching the
plug website.

I can't speak for the PLUG staff, but it appears to me that
www.plug.phoenix.az.us resolves to 66.98.190.6 (as you indicated) which
is IP space owned by a hosting company called "Everyone's Internet" out
of Houston Texas (http://www.ev1.net). They appear to be hosting the
website on Apache/Linux (good!) and using vhosts, which means it's
probably not a dedicated server. Since they are using vhosts you can't
surf directly to the resolved IP address. Apache is using the hostname
requested in the URL to determine which site to serve up on the shared
server. In fact, if you surf directly to http://66.98.190.6 you will be
redirected to an SSL-encrypted site admin page (bad idea - IMHO!).

As for traceroute falling down, well it's pretty common for hosting
providers to drop icmp and udp traceroute packets. It's often a matter
of survival for them. We can thank all the wormdows infestations for
that. NOTE: your traceroute (and mine) fails at the last hop in
Houston. Probably at ev1's front door. ;-)


This is all guess work on my part, but here is a terminal log to base it
on...

Our traceroutes seem to meet at chndbbrc01-pos0101.rd.ph.cox.net
(68.1.0.164) and stay together for the rest of the trip. Doesn't seem
to be a problem with the Cox routing.
