Starting at 12:00 UTC on Thursday, 15 October 2026, we’ll migrate the publick8s AKS cluster (Azure), which hosts our public services, from the CDF subscription to the new publick8s-sponsored cluster in our Azure Sponsored subscription.

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
• plugin-health.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, infra.ci.jenkins.io, weekly.ci.jenkins.io, release.ci.jenkins.io, cert.ci.jenkins.io
• issues.jenkins.io (Jira)

Temporary disruptions (slow requests or outage of a few minutes) on all user facing services.
