  • 2017-09-27:  HCC Tusker Downtime Planned - Oct 5, 2017
    Category:  Maintenance

    This maintenance outage for software updates affects Tusker only. Jobs which cannot complete before October 5th at 9:00am will be held in queue until the maintenance is complete. A follow-up announcement will be posted when the system is ready for production use.


    To minimize the impact to running jobs we are declaring a downtime for Tusker to complete this work. We will use this maintenance window to update various software components across the cluster. The Tusker login node will also be updated and will require users to log off. Users will be denied access to the Tusker login node until the maintenance is completed.
