Is there any Nagios monitoring in place or is there the need to have
some external reliability monitoring in place?
I can set up a Nagios machine to check the HTTP status of PyPi. Also,
if the earlier described path of PyPi mirroring my the community is
chosen I can happily have a server serving PyPi packages in the
