UPS Maintenance in SDH 158

by

At 11 AM today we will be replacing batteries and performing maintenance on a faulty UPS located in our primary server and network room for Sutardja Dai Hall. No service interruptions are expected. However, in the event of a failure, there may be a ~5 minute loss of wired and wireless networking in Sutardja Dai Hall, as well as a loss of the NetApp network file storage for the EECS Instructional Labs. The maintenance is expected to last for approximately one hour, but two have been allotted in case of complication.

Intermittent network outage

by

We are seeing wireless and wired network disruption on the EECS networks, most noticeable on the wireless networks.

Campus reported an unscheduled network outage earlier this morning, still in progress (check http://ucbsystems.org/ for updates), but it’s as yet unclear whether this is related. Updates will be posted here as they are made available.

Cory Hall 5th Floor Switch Failure

by

On Friday night, we experienced a failure of an access switch on the 5th floor of Cory Hall. This has resulted in a loss of connectivity to approximately one third of the wired devices and wireless access points on the floor. We are currently in the process of replacing the switch and should restore full connectivity by 12:30 PM.

EECS Network Scheduled Outage on Mar. 29 2014

by

We will be having a large scheduled outage of the EECS network in order to physically relocate some core devices as Phase Three of a project to overhaul the EECS network core. This maintenance will occur between 10AM and 6PM on Saturday, March 29, 2014. We do not anticipate the outage to last for the full eight hours, but extra time has been allotted in case of complications.

Expected impacts of this outage include:

– Internet connectivity to all EECS Wired buildings* will be offline
– Soda Hall wired and wireless networking will be entirely offline
– BWRC will be isolated from EECS and unable to access the Internet or EECS network resources
– Wireless networking in EECS Airspace** will be unavailable (the networks will continue to be visible in some locations, however the underlying network services will be offline)
– EECS Wired buildings other than Soda Hall and BWRC should retain connectivity and access to EECS network resources (filers, AD, etc.), but to reiterate, the Internet connection will be unavailable.

We apologize for any inconvenience that this maintenance will cause. For any questions or concerns about the maintenance, please email networks@eecs.berkeley.edu.

Thank you, IRIS Network Group

*EECS Wired buildings are Soda, Cory, and Sutardja Dai Halls, and the BWRC

**EECS Airspace includes Soda, Cory, Sutardja Dai, Calvin, and Blum Halls, as well as the Sibley Auditorium, Hearst Memorial Mining Building, and BWRC
