FYI, gabelmoo is passing directory requests through Apache for two
reasons: First, I have been using Apache as a first attempt to measure
how long clients take to download network statuses in order to derive
how fast clients are; this functionality is now in 0.2.2.0-alpha-dev, so
that Apache is not required anymore for this:
http://archives.seul.org/or/cvs/Jul-2009/msg00244.html
Second, I'm using port 80 both for serving the Tor directory and for
serving files for performance measurements:

Eeeeuww! That's hideous. Why would someone configure a mess
like that when they could just as easily use an RDR rule?

How would a typical user know that the "proxy" in question was an
apache server on the other end? Ugh.

Bummer. Thanks for the explanation, Roger.

I've got similar messages too, always in conjunction with 'Got a bad

80.190.246.100:80 is the DirPort on gabelmoo, one of the v3 authorities.
So your relay was trying to get an updated version of the v3 consensus
from gabelmoo.
It looks like the way gabelmoo is listening on port 80 is by proxypassing
it through apache. You can read more about that approach in this poorly
organized faq entry:
https://wiki.torproject.org/noreply/TheOnionRouter/TorFAQ#ServerForFirewalledClients
and at that particular moment, for some reason apache decided that
sending back a 502 proxy error was better than passing your request on.
For example, I bet this could happen if the gabelmoo relay was down at
the time.

warning message question
Saturday morning, I got the following message.
Jul 25 09:33:57.004 [warn] Received http status code 502 ("Proxy Error") from
server '80.190.246.100:80' while fetching consensus directory.
Can anyone explain the situation(s) that can result in such a message?
Thanks in advance!
