    CUIT will be performing network maintenance in the School of Social Work on 11/4/15 from 7:00-7:30 a.m.  During the maintenance window, there will be two brief outages as switches serving the building are rebooted.  One outage will affect parts of the 6th and 7th floors.  The other outage will affect parts of the 8th and 9th floors.  Each outage should last approximately 5 minutes.  Ethernet, wireless and netphone service will be unavailable while the switches reboot.

  • Yeti HPC
    11/03/2015 - 08:30pm to 11/04/2015 - 07:36pm

    Access to this service was restored after moving this functionality to another server, during the scheduled maintenance downtime which ended around 7:30 this evening.


    The Yeti head node became unreachable starting at approximately 8:30 pm. Active user jobs are continuing to run but users cannot access the cluster and no new jobs can start. The problem is being investigated. *Update* The cause was most likely a hardware failure and the system will be serviced in the morning. As the cluster has a previously scheduled maintenance window starting at 8 am it has been decided that in order to minimize the effect on running jobs the head node will remain offline until then. The users have been notified.
