Network interruption at EECS border
A little after 1pm today, we experienced a loss of network traffic at the EECS border. Typical network use within EECS continued to work, though it appeared we were cut off from the rest of campus, and the outside world.
Staff investigation found the problem to be at or with one of the department border firewall devices. The secondary firewall device has been made primary now, and traffic is routing properly. Staff will further examine the problem firewall device, to narrow down the specific cause.

EECS Full Network and Service Outage, Thurs. 12/22/16 7:30AM
We will have a full system shutdown on Thursday, December 22nd at 7:30 AM to perform necessary fire and emergency power testing in our server rooms. The entire EECS network and all hosted resources will be offline during this maintenance.
This will affect networking in the following locations:
Wired and wireless networks offline:
* Soda Hall
* Cory Hall
* Sutardja Dai Hall
* Jacobs Hall
* BWRC
Wireless networks offline, wired remains online:
* Blum Hall
* Calvin Lab
Hosted resources such as the EECS website, file servers, etc. will be offline and globally inaccessible.
The facilities maintenance window is scheduled from 7:30 AM to 1 PM, but we anticipate the network and critical services should be back by 11AM if all goes well.
The intent is to perform these tests annually going forward; however we will learn from this year’s procedure and aim to keep more critical services online in the future.
If you have any questions about this maintenance, please contact help@eecs.berkeley.edu.

Cory Hall networking down as of early Dec 10
At about 1:30am Saturday, monitoring software indicates that our link from Soda Hall to Cory Hall went down, resulting in all Cory Hall hosts being offline/unreachable. Staff will investigate possible hardware failures, and hope to restore service later today.
EECS-Secure and EECS-RADtest authentication in all locations (not just Cory Hall) were also affected due to a single point of failure located in Cory Hall, which is set to be rectified in January.

Network disruption
Network staff are investigating two failed switches. The switch failures are affecting a number of hosts in the department; in particular, communication between hosts on the 128.32.48.0 subnet (165 Cory Hall) and the NIS/DNS servers cronus and rhea.
*Update*: as of 10:28am, communication between the 48 subnet and cronus/rhea was restored.

EECS Internet Outage, 9/22/16
EECS’ Internet connection went down at approximately 6AM due to a loss of default routes normally advertised by campus BGP. The issue was isolated and the campus NOC restored the routes shortly before 10AM.
We believe network connectivity to be fully restored at this time. If you continue to experience issues, please email help@eecs.berkeley.edu.
