Resolved after 1h 30m of downtime. December 12, 2025 at 10:30 AM UTC

[Final message] Upgrade completed without any issue. We’ve done it today only as yesterday GitHub was too unstable to perform it without hitting issues when pulling terraform providers or helm repositories.

[Initial message] Friday 12 December 2025 at 09:00 UTC, we’ll upgrade the AKS(Azure) cluster privatek8s to Kubernetes 1.33.5. It should take between 30 and 60 min.

Expect multiple restarts and downtimes for the infra.ci.jenkins.io and release.ci.jenkins.io controllers along with the github-comment-ops bots.
