Recovering from campus power issue
Resolved - No further issues have been reported.
Dec 22, 13:36 CST
Monitoring - Users should be able to login to our systems again. Let us know if you are encountering issues with the system.

Identified - Yesterday morning campus had an issue with electrical power (https://outages.doit.wisc.edu/outage/94c88500af43ffca0566394402ba67a224b548df45).
While the power issue was quickly resolved, the interruption of power requires that we manually recover some CHTC services.

Users may have issues logging in and jobs may have been interrupted. We should have services returned to normal later today.
