[Final Message] The cluster and all its services were up and running at 10:02am UTC after many mitigation and operations from the Jenkins Infra team.
[Update] At 09:20am UTC, all services were down due to internal AKS outage (combination of network issue and Azure forbidding us to spin up new VMs).
[Update] We tried to apply mitigations between 08:45am UTC and 09:15am UTC without any success (draining AKS nodes to restart services on fresh VMs).
[Initial Message]
Starting on Tuesday 16 June 2026 at 07:30am UTC, the cluster publick8s hosting our public web services such as updates.jenkins.io, get.jenkins.io, LDAP and many others started to drop incoming TCP connections.
Users started to see random “timeout connections”.
