Excellent, thanks!

I notice on that list that in some cases there are contacts for the
CC.freebsd.org domain listed, but no contacts are listed for the admins
of the servers themselves. Does $someone have the ability to contact them?

That sounds fine, except in the cases of truly old stuff like packages
for 5-current (and arguably for 6.x stuff as well, but I'm less
concerned about that than I am 7 year old stuff for an unsupported
branch). Has there ever been an attempt to bring some kind of order to
the chaos?

Ok, I've cc'ed both, anyone who replies should feel free to take
developers@ off the cc list.

Ok, done.

On a more long term basis one wonders what kind of adult supervision is
in place for this stuff. In 5 minutes testing I found 2 broken ftp
servers out of 14. Isn't this something that we should be monitoring?
