[Tf-openci-triage] [Maintenance] - ci.staging.trustedfirmware.org down time 2023-12-20

Hello All,

The server will stop processing jobs on 2023-12-20 at around 6:00pm UTC, as the server will be put into "Shutdown mode".

This downtime is needed in order to upgrade Jenkins and some of its plugins to the latest LTS release.

Start: 2023-12-20 07:00pm UTC End: 2023-12-20 09:00 UTC

If this upgrade remains stable in staging, we will plan to upgrade ci.trustedfirmware.org and mbedtls.trustedfirmware.org shortly after 2024-01-03.

Regards,
