[Ci-users] [infra] : Planned outage : Jenkins/CI environment

Due to some needed software updates, we'll have to shutdown and restart jenkins on the 'legacy' ci.centos.org setup (reminder : moving to openshift would be great and we'll have to put a hard deadline for this if some tenants are still on the old setup)

Migration is scheduled for """"Tuesday September 28th, 9:00 am UTC time"""". You can convert to local time with $(date -d '2021-09-28 09:00 UTC')

The expected "downtime" is estimated to ~30 minutes , time needed to put jenkins in "shutdown/quiet mode" , wait for some some jobs to finish, update and restart jenkins.

Thanks for your comprehending and patience.

on behalf of the Infra team,
