    Data Center Firewall Replacement August 3rd 9am-3pm

    NOTE: The following is in addition to our regular monthly maintenance at the same time.

    On Monday August 3rd in addition to our monthly maintenance, the primary firewall in one of the data centers will be replaced. This will interrupt storage and home directory connectivity to the cluster and therefore the cluster must be idle for this cutover. General storage access will also be affected during this period.

    This has been scheduled with networking to coincide with our monthly maintenance but will run longer. 9AM - 3PM

    - All jobs still running on August 3rd will be canceled -

    On the morning of August 3rd:

    • Any running jobs will be canceled

    • All partitions will be closed

    • Login nodes will be shut down

    • The Networking group will commence work

    Once the firewall work is complete and tested, we will re-open the partitions and boot the login nodes. ETA 3PM

    Due to the disruptive nature of this work, we want to advertise this with a longer advance notice. Normal maintenance emails will be sent per usual starting next week and will contain a condensed version of this information
