Yes, it's been served by some machine at the IMC -- not certain which,
but it's different from www.ucimc.org.

The public IP address is www.anti-war.net = 75.145.177.75

In the past, I've been logging into zeco.ucimc.org (which may call itself
imsahp.ucimc.org) to edit the web site (/var/www/aware/website),
but I'm not certain whether zeco/imsahp is the web server or
whether it just shares the web-tree filesystem with the server.
zeco.ucimc.org and imsahp.ucimc.org have the same 75.145.177.75
IP address listed in the public DNS.

*** Are you able to log into imsahp from inside the IMC today?
If so, what IP address does it have?  (What does "/sbin/ifconfig" say?)


On Monday, when this was starting to fail, I was seeing that
"ssh zeco.ucimc.org" would sometimes succeed, and sometimes
report "No route to host", on attempts even just a few seconds apart.
