Hi all,

For the first time in CentOS history, we'll have two version going EOL the same year, at just some week intervals, so we should already be prepared about this, and the sooner, the better.

Per https://www.centos.org/centos-linux/ and https://www.centos.org/centos-stream/#centos-stream-8 : - June 30th 2024 for CentOS Linux 7 - May 31st 2024 for CentOS Stream 8

At the infra side, there are services that we still need to see working, so we already started to add el9 support to our ansible roles and some services are already (or will be soon) migrated to el9.

I intend to send multiple mails in the next hours/days about identified applications for which we're still unsure if we should migrate these , or just let them behind (decommission), so if you see a topic/subject for an application you're interested in, feel free to participate in that specific thread (easier to read/follow than just everything in one email thread). These emails should start with something like "RFC (Request for comments) : future of <app>"

Let me just announce here in advance the (public) infra services running on CentOS 7 that will just disappear when CentOS 7 itself will be EOL (and so not receiving any update anymore) :

- mirror.centos.org : all Stream 9 (and above) mirror content is now on its own dedicated mirror.stream.centos.org CDN setup, so there is no need to keep an empty mirror.centos.org vhost with no content, as all content will be moved (as usual) to vault.centos.org. So mirror.centos.org A/AAAA records will be removed completely. (or we can just have a simple vhost with a redirect to mirror.stream.centos.org)

- mirrorlist.centos.org : from Stream 9 (and above), it's using Fedora infra mirrormanager instance for metalink= instead of mirrorlist= in .repo files. We'll just decommission our mirror crawler (also running with a mix of perl/python2 code), so not validating any mirror for legacy/EOL releases. mirrorlist.centos.org A/AAAA records will be removed in the following weeks after c7 will be EOL'ed.
