Monday 15 December 2025 at 08:30PM UTC, we’ll upgrade the AKS(Azure) cluster publick8s to Kubernetes 1.33.5. It should take between 60 and 120 min.

The expected impacts are:

Restart of the following services, with a downtime between 2 and 15 min (depends on Azure Storage systems):

• ldap.jenkins.io
• weekly.ci.jenkins.io
• incrementals.jenkins.io

Temporary disruptions (no Log-in/log-out possible during the LDAP restart) on:

• accounts.jenkins.io
• ci.jenkins.io, trusted.ci.jenkins.io,…
