DNS Resolution Issues, 8/31/21
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.

We will be performing a needed firmware upgrade on the Soda Hall core router at 6AM on Sunday, August 29th. This will cause a disruption of all traffic in and out of the EECS network, as well as traffic between the various Soda Hall networks. We expect this outage will last for between 5 and 20 minutes.

Rolling Wi-Fi Outages, 5/18 – 5/28
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.
