All(?) CI jobs failing with errors downloading packaging

I see a lot of the following errors (AFAIK, on ALL CI jobs): DEBUG util.py:421: http://proxy.phx.ovirt.org:5000/fedora-updates/24/x86_64/u/unzip-6.0-30.f...: [Errno 14] HTTP Error 503 - Service Unavailable DEBUG util.py:421: Trying other mirror.
