EECS-Secure wifi outage due to power failure in Soda Hall

by

A brief power outage in Soda Hall led to an outage in the EECS-Secure wifi, though other EECS wifi SSIDs remained operable.

The cause of the outage was due to the radius servers failing to automatically power on again once power was restored, so they had to be started manually. We will review the configuration of these servers in an effort make them more resilient to such outages.

project.eecs will have a short disruption of service at 6:30 pm today. This maintenance should last no longer than 15 minutes, and home.eecs should takeover for project during the downtime. Most home directory accesses should recover gracefully from the disruption. Windows mounts may require a re-connection.

Apologies for the short notice. Normally at least 24 hours would be provided before the maintenance window, but this work is required to prevent a more serious problem.
