Unexpected Power Outage at Campus Datacenter

by

A test of temporary generator power at the campus Data Center didn’t go well, and the Data Center was shut down at about 11am this morning. This affects a number of IRIS services, such as lists.eecs (mailing lists) and IRIS apps (account and system registration requests), and is also having an impact on wifi authentication.

Please see the Berkeley Status Dashboard for updates: https://berkeley.statusdashboard.com/event/192049/
