We've been operating a Debian mirror since approx. ten years (it also hosts a mirror of Ubuntu, Tails and Debian Openstack Backports repository). This has historically been a great way to contribute back to our favourite OS. But Debian defaults to the deb.debian.org CDN since many years and that shrank the use of the traditional mirrors significantly.
Despite being part of the ftp.us.debian.org mirror rotation our mirror is hardly used these days, even despite idiotic AI scrapers hitting the server randomly and excessively, our bandwidth usage practically never exceeds 10% of the available bandwidth (and usually even less than that).
The current server is ending it's hardware lifespan, so in the current state it currently does not really make sense to refresh it, so we'll likely decommision it entirely.
