That page describes the target timeline that would be followed in an
ideal world with unlimited engineering resources. Sometimes timelines
slip, for example right now there's 225 hosts running Debian Buster in
the Wikimedia "production" environment and another ~200 within Cloud
VPS even though Buster was according to that policy supposed to be
gone sometime last year.
Currently we tend to drop support for a release from Cloud VPS once
the other Wikimedia environments are far enough in the migration that
we start blocking support removal from shared infrastructure, or once
the Debian LTS project drops support for a specific release. The
latter is happening for Buster soon so we recently announced removal
of Buster support from Cloud VPS (see below).
I shows support ending as follows:
Buster: September 2023
Bullseye: September 2025
I have the impression that VPS support for Buster is ending in May or June of this year.
The plan for Cloud VPS is documented at
<https://wikitech.wikimedia.org/wiki/News/Buster_deprecation>:
"Support for Debian Buster ends on June 30th, 2024."
Also, if I look at an instance's OS in Horizon I
see
debian-12.0-bookworm (deprecated 2024-04-10)
I'm not clear why this would be deprecated already.
This is the specific version of the Debian Bookworm base image that
your instance was created with, it means that on 2024-04-10 a new
image was built to replace that one. That is unrelated to the process
for dropping support for an entire OS release.
