    The Slurm upgrade to 23.11.4 was completed successfully during maintenance. However a complication with the automation of Slurm's cryptographic keys occurred during the upgrade which caused nodes to lose the ability to talk to the Slurm master. The Slurm master therefore viewed those nodes as down and requeued their jobs.

    All jobs on Cannon and FASSE were requeued.

    This is deeply regrettable but the chain of events which caused this could not be foreseen.

    To check the status of your jobs, see the common Slurm commands at:

    Infiniband Nvidia MQM9700 firmware update to the latest version 3.11.3002

    -- Audience: All cluster users

    -- Impact: No direct impact (this is networking firmware, not GPU firmware)

    -- Jobs will be paused to accommodate this update

    Internal services updates

    -- Audience: FASRC internal services including: foreman, atlantis, puppet, terraform

    -- Impact: No user-facing impact

    Login node and OOD/VDI reboots

    -- Audience: Anyone logged into a login node or VDI/OOD node
