Re: Jenkins Maintenance: 2020-10-19 1700 UTC to 2200 UTC

Maintenance has been completed successfully. All service are available.

As part of maintenance we downgraded the Gerrit Trigger plugin in Jenkins to avoid a re-occurrence of the incident we had today. It appears there is a defect in the latest version of the plugin that causes Gerrit triggers to stop triggering builds in Jenkins causing the queue to grow out of control and affect the stability of the Jenkins system. The root cause is unknown at this time. The workaround is to restart Jenkins.

If you experience any issues, please open a ticket at

Thank you,
Anton & Vanessa
