Public bug reported:

This is a known and fixed upstream bug: https://bugs.debian.org/cgi-
bin/bugreport.cgi?bug=826104

The package tries to update its data every month from an apparently not
so strong host, causing a classic thundering horde DDoS.

Debian fixed this by deciding the cronjob wasn't such a good idea after
all and simply removing it.

The fixed version of the package is in zesty and above, while xenial
still has a bad version.
