Maintenance on ci.jenkins.io →

trusted.ci.jenkins.io cert.ci.jenkin.io ci.jenkins.io

[Final Message] Operation completed successfully

[Initial Message] Tuesday March 10 2026, starting at 09:00 UTC, the Jenkins controllers and agents on trusted.ci.jenkins.io, cert.ci.jenkin.io, and ci.jenkins.io will be upgraded to use JDK25 at runtime instead of JDK21.

This operation will require controller restarts and agent reconnections. A short service disruption is expected during the maintenance window.

ci.jenkins.io enforced login and users cleanup →

ci.jenkins.io incrementals.jenkins.io

[Initial Message] On Wednesday 28 January 2026 at 18h15 UTC, ci.jenkins.io will require authentication with a Jenkins LDAP account to allow reading pages.

As part of this change, the users database will be wiped out, effectively removing all API tokens and personal preferences. Direct consequence: incrementals.jenkins.io won’t be able to deliver new incremental releases until a new API token is generated.
