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.

Wireless Network Maintenance, Fri. 6/17/16 10PM

by

We will be performing a major software upgrade of the wireless controllers at 10PM on Friday, June 17th. This upgrade includes a number of needed security and feature updates.

This will affect wireless networks in the following buildings:
Soda Hall, Cory Hall, Sutardja Dai Hall, Blum Hall, Jacobs Hall, Calvin Laboratory

During the upgrade all wireless networks will be unavailable. We have not upgraded this platform before so we are uncertain how long the outage will last, but we anticipate a minimum of 10 minutes and (barring catastrophes) a maximum of around a half hour.

Please contact help@eecs.berkeley.edu with any questions or concerns about this maintenance outage.

The Department’s mailing list server lists.eecs.berkeley.edu has been experiencing occasional delays in sending messages. Some outgoing messages have been delayed by as much as 40 minutes. As part of the debugging process we are patching and rebooting the server around 10:40am.

Staff are investigating the problem and will post updates here as we learn more.

Cory Hall Server Net Maintenance, 6/2/16 9PM

by

We will be performing maintenance on the Cory Hall restricted and server networks tonight at 9PM. Machines on the 128.32.244.0/25 and 169.229.60.128/25 networks (primarily, machines located in 165 Cory) will experience a brief loss of connectivity which we expect to last for less than 10 minutes.

The purpose of this maintenance is to migrate the default gateways for those subnets to a different router to address a possible traffic hairpinning issue. No reconfiguration will be necessary by sysadmins and there should be no visible lasting effect (other than reduced packet loss and/or latency on these networks).

Please contact help@eecs.berkeley.edu if you have any questions or concerns about this maintenance outage.
