Wireless networks on the 7th floor of Soda Hall were offline beginning at 17:31 yesterday (8/18) due to a faulty switch PoE module. Unfortunately, we were not made aware of this until about 15:00 today.
We have replaced the faulty switch, and service was restored around 17:30.
We will be performing maintenance on our border router at 6AM on Sunday, August 1st which will cause a 5-10 minute disruption of the network path in and out of the EECS network. During this time, all EECS networks will be severed from campus and the Internet.
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.
As of 2:21 pm, networking for Sutardja Dai, Blum, and Calvin Halls is offline. Staff are en route to campus for further investigation.
Update: network connectivity was fully restored at 6:00PM when certain hosts which were causing instability were removed from the network. We will follow up tomorrow with the sysadmins of these hosts to try and prevent future incidents.
