git pull fails from elpa.gnu.org

[Stefan Monnier]

The cron job on elpa.gnu.org is having trouble that I don't understand.
More specifically, it does:

    + cd ../elpa
    + git pull
    fatal: unable to access 'https://git.savannah.gnu.org/r/emacs/elpa/': The
    requested URL returned error: 502

The weird thing is that when I ssh into elpa.gnu.org and run the exact
same command, the `git pull` works without a hitch.

Any idea what might be going on and how I could try and track it down or
(even better) fix it?  I'm getting a bit tired of playing the "human
cron job".
