Cory Hall networking down as of early Dec 10

by

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.

Loss of Battery Backup in 290 Soda Machine Room

by

Our primary machine room, 290 Soda, has lost battery backup power, due to the explosion of one or more batteries in the APC cabinet. These batteries were recently installed (May, 2016); building staff are coordinating warranty coverage and replacement.

No systems were affected by the loss of battery backup, but at this time all systems in 290 Soda are fully reliant on building power. This includes many IRIS and Instructional systems and services.

We will update this News item with the expected timeline of replacing the battery backup, as that information becomes available.

Replacement of batteries may take a week or more, depending on availability from the vendor.
