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.

Packet Loss at EECS Network Border

by

We are seeing some dropped connections between the EECS network and the outside world (including the rest of campus). This is affecting communication in both directions.

You may experience symptoms such as webpages not loading, systems not responding to ping, and remote login sessions terminating unexpectedly.

Our network staff will work to identify the cause, and restore reliable networking.

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

Research Network unable to reach outside of EECS

by

At around 4:00PM today, the “Millennium” Research Network became unreachable from outside of the EECS Department.

While resources within the EECS Department remain acccessible, systems will be unable to get outside of the department.

It is not clear at this time how this might be related to problems occurring with the larger Departmental EECS Network that started occurring in the same time frame.

Research staff are working with EECS networking staff to bring networking back up and will post updates as they happen.

Network outage in NanoLab

by

The switch in slot 2 of citsum6M81 in the NanoLab on the 6th floor of Sutardja Dai Hall has failed. As a result, some wired networking services on the 5th and 6th floors are likely impaired. Network staff are currently preparing a replacement switch and intend to have the outage resolved early this evening. We apologize for any inconvenience caused by this outage.
