[Jenkins public infra (*.jenkins.io)] LDAP disruptions expected during Kubernetes 1.34 upgrade

[Jay Francis]

Hello dear Jenkins contributors,

As described in https://status.jenkins.io/issues/2026-06-03-maintenance-azure-publick8s-1-34/, on Wednesday 3rd June at 9:30am UTC we'll proceed with a Kubernetes upgrade of the Jenkins infra public cluster.

Expect disruption with logging-in / out on all the "*.jenkins.io" or "*.jenkins-ci.org" websites (including ci.jenkins.io, JIRA and Artifactory).

There might be an outage on update-center (updates.jenkins.io) of a few seconds as in the previous Kubernetes upgrades.

Builds and deployments should continue as usual.

The operation is expected to take between 30 to 120 minutes.

For the Jenkins Infra team,

Jay Francis

[Damien Duportal]

We are starting the operation

upgrade went well, no impact on production.
