Interesting thought! I just grepped for a few of the "abusive" hosts.
These hosts are downloading packages, including some "basic" ones like
perl, curl, python setuptools.

I'll relax the fail2ban rules a bit and see how things evolve over time.
Maybe everyone needs to rebuild everything once now, which obviously
causes a bit of traffic.

My expectation is that traffic is going to be higher in the next 6 months as various systems are getting moved from CentOS 7 to some newer release. This upgrade process will require a system to be first updated to the latest '7' and many have had updates turned off for years.. then there will be a download and update to EL8 or EL9 depending on what they are doing which will also create a spike in traffic.
