We will be performing an emergency upgrade of our wireless controllers tonight beginning at 9:30PM to address a bug which has been causing periodic controller crashes that bring down the wireless network. The last outage generated by this bug was on Jan. 18, but we also experience more frequent crashes that do not affect production due to redundancy.

The controllers have the capability for a hitless upgrade (upgrade without affecting service), however we have had mixed experience with this feature in the past. We expect there may be an outage of 10-15 minutes while the controllers reload after the upgrade.

This maintenance will affect wireless networks in Soda, Cory, Sutardja Dai, Blum, and Jacobs Halls, as well as the Calvin Lab, BWRC, and BiD Lab in HMMB.

Please direct any questions about the upgrade to help@eecs.berkeley.edu.

UPDATE

Staging took longer than anticipated but the upgrade was completed around 10:20PM.

We will monitor the system to ensure that the new software has fixed the crashes.
