I've recently noticed that https://ftp-master.debian.org/ is not accessible over
tor.  I get "The connection has timed out. The server at ftp-master.debian.org
is taking too long to respond."  in the same browser where everything else is
responsive.

Curl says:

$ https_proxy=http://localhost:8081 curl https://ftp-master.debian.org/new.html
curl: (56) Received HTTP code 500 from proxy after CONNECT

This works fine:
https_proxy=http://localhost:8081 curl https://www.debian.org

As discussed in #debian-ftp

It seems that based on the box's iptables, the blocking is coming from the
hoster (Brown University), not the machine itself.  One potential solution is
moving the web pages off that box to a public webserver.  That would also
improve the security profile of that box.
