Firewall Changes to Soda Hall 3rd and 4th Floor Networks, Mon. 12/20

by

At 6AM on Monday, December 20, we will be migrating these two Soda Hall networks to our new border firewall:

128.32.112.0/24 (Soda Hall 3rd floor: primarily rooms 330, 340, and many offices along the East wall)
128.32.132.0/24 (Soda Hall 4th floor: primarily RISE Lab)

There will be a brief interruption to these networks as they are migrated. After the migration, we encourage system administrators to test that traffic across the firewall is behaving as expected.

Please contact us at help@eecs.berkeley.edu with any questions or concerns.

DNS Resolution Issues, 8/31/21

by

We are currently seeing an issue where eecs.berkeley.edu, cs.berkeley.edu, banatao.berkeley.edu, and possibly other related DNS names are not resolvable from campus networks or from the Internet. As a result, many websites appear down and emails may bounce.

We have contacted IST, who operate the DNS servers that answer these requests from non-EECS networks, and they are investigating.

Name resolution from EECS networks using EECS DNS resolvers is working properly.

Part of the Soda 4th floor wired network (primarily RISE Lab) was offline today between 15:34 and 15:46 due to a misbehaving private network. The private network has been temporarily disabled and service has been restored.

Rolling Wi-Fi Outages, 5/18 – 5/28

by

Beginning Tuesday, May 18th, we will be performing wi-fi upgrades in all EECS network service areas (except BWRC and HMMB). Work will generally proceed floor-by-floor, with each building experiencing rolling wi-fi outages over a two to three day period. All wireless networks will be offline: EECS-Secure, EECS-PSK, AirBears2, eduroam, and CalVisitor.

Please see the schedule below for information specific to your building. If you are currently working on campus, and depend on the wireless network in these locations, please consider working from an alternate location during your building’s maintenance dates. We also recommend checking this post regularly in case of schedule changes.
