EECS wireless RADIUS patching

by

On Thursday, May 13 from 9:00 to 10:00PM, there will be a patch to be applied for EECS department RADIUS server. This patch will fix a few issues in configuration replication between the Cluster nodes. Public facing services which depend on RADIUS are EECS-Secure, EECS-Open, and EECS-Guest authentication and accounting. We do not expect this work will cause an outage for these services, as the second, redundant server will remain operational during this time and should not be affected by this work. A one hour outage window has been scheduled in the event of unexpected problems.

Please contact with help@eecs or networks@eecs if you have any question.

6th floor Soda switch replacment

by

Due to a power supply failure, I will be replacing one of the stacked switches which serves the 6th Floor of Soda Hall. The switch is currently operating only on an external redundant power supply.

The outage will definitely affect half of the connections on the 6th floor for about 20 minutes; if a full stack reboot is required (likely) the rest of the 6th floor connections, including wireless, will be briefly disrupted.
