The attempt to upgrade and switch Jenkins ran into some issues last time. Meanwhile these have been fixed. Therefore we have another window now.
Tomorrow, July 7th 2026, 15:30–16:30 UTC, CI / jenkins may not be working. https://wikitech.wikimedia.org/wiki/Deployments#Tuesday,_July_7 An outcome of this will also be that we will upgrade from Java 17 to Java 21 and Jenkins will be running on a dedicated host on a stable and supported distro version. We apologize for the inconvenience.
