UNPLANNED OUTAGE
----------------

A brief power outage at the Merit/Ann Arbor MACC Data Center at 9:41am caused a number of problems for University systems. While power has been restored to the MACC, many services remain out. UM-Dearborn ITS does not have a estimated time of restoration for all services. Ann Arbor and Merit is working to restore systems as soon as possible. 

Due to this power outage, users on the UM-Dearborn campus can continue to expect problems authenticating to UMICH email, Canvas, and other services requiring shibboleth. We are also experiencing network delivery problems to the ECEC on Rotunda Drive.


UPDATE: MACC Data Center Outage, 5:00 PM, 2/18/2017 
  • Network at the ECEC office on Rotunda Drive has been restored.
  • UMICH email and Shibboleth authentication services have been restored.
  • As of now, no known issues specific to Dearborn campus have been identified.
