    From Harvard University RC:

    NESE is scheduling a hardware repair for 12/11 to one of disk cache management servers for NESE Tape.

    The scheduled repair will not interrupt the Tape service, but you will likely experience performance degradation in interacting with the archive on 12/11 during the maintenance.

    This maintenance will not affect the NESE Disk service.

    The scheduler is experiencing a high load at the moment which may manifest as slowness, timeout or general instability for job scheduling. We are actively working to mitigate this.
