  • 2011-08-08:  PrairieFire and Merritt affected by Power Outage
    Category:  System Failure

    A power outage in Lincoln affected both PrairieFire and Merritt last weekend. While most services were restored to PrairieFire, jobs were not restarted, and after further inspection some further maintenance (in particular for the IB) was found to be required. Users will be notified via this thread once full system functionality is restored. Merritt remains unavailable for the time being as well.


    A power outage during the weekend knocked PrairieFire (and SandHills) worker nodes off line-- thus, all jobs were killed. Users are asked to wait to deploy jobs until further maintenance is completed. Merritt will remain offline for the time being.
