At about 1:30am Saturday, monitoring software indicates that our link from Soda Hall to Cory Hall went down, resulting in all Cory Hall hosts being offline/unreachable. Staff will investigate possible hardware failures, and hope to restore service later today.

EECS-Secure and EECS-RADtest authentication in all locations (not just Cory Hall) were also affected due to a single point of failure located in Cory Hall, which is set to be rectified in January.

The Cory Hall networking outage was caused by a failed UPS in the primary networking closet. Most circuits in this networking closet are hard-wired to the UPS.

Power has been re-routed to live circuits on building power, and building management staff has been notified of the failed UPS.

At about 9:35pm, the same equipment had another power outage, due to tripping a breaker. We have redistributed the load, and restored power to the affected equipment.

We will continue to monitor the situation over the weekend.
