The clusters are currently running Kubernetes 1.23 which went EOL on 2023-02-08. Kubernetes 1.31 is running in production (wikikube) since July 2025.
It's time to upgrade since we plan on moving to the next (>1.31) Kubernetes version already and we aim to support not more then two versions at the same time.

DPE SRE does not have time right now to move forward on this upgrade. We will try to start on this work before the end of Q3. Please ping us if you don't see the progress that you would like to see!
Please note that https://phabricator.wikimedia.org/T383553 needs to be done as part of the upgrade :)
