December 16, 2022 by Derek Calderon

Between 11AM and 4PM on Wednesday, December 28th, we will be performing maintenance on the Soda Hall core router. Most Soda Hall wired networks will not be affected by this maintenance due to redundant links. However, Soda Hall and BWRC wi-fi, as well as BWRC’s uplink to the outside world, will experience a number of interruptions during this time.

EECS Network Border Maintenance, 12/27 1-2PM

December 16, 2022 by Derek Calderon

Between 1 and 2PM on Tuesday, December 27th, we will be performing a firmware upgrade on one of our two redundant border routers which connect the EECS networks to Campus and the Internet. No interruption is expected, as the other border router which is not being upgraded will be able to handle all network traffic during this maintenance.

Update 2:15P: This upgrade has been completed and both border routers are back online. Please email us at help@eecs.berkeley.edu if you notice any network issues.

EECS Network Border Maintenance, December 13-14

December 12, 2022 by Derek Calderon

This week, we will be performing network maintenance to complete the decommissioning of our old border firewalls. The work will be performed in two stages; the first between 11AM-12PM on Tuesday the 13th, and the second between 11AM-12PM on Wednesday the 14th.

We do not expect this work to have any impact to network connectivity, as the vast majority of traffic flows were migrated to our new firewall earlier in the year.

Please email help@eecs.berkeley.edu if you have any questions, or if you notice any unusual network behavior.

Update 12/14: This work has been completed without any network impact. Please email us at help@eecs.berkeley.edu if you notice any issues.

EECS Border Firewall Update, 11/3 1PM

November 3, 2022 by Derek Calderon

This afternoon at 1PM, we pushed a configuration change to the EECS border firewall which affects the firewall’s access to various configuration resources. This change was tested and we anticipate no effect; however please email help@eecs.berkeley.edu if you notice any of your machines or services suddenly become unreachable from outside the EECS network.

Cory Hall 1F Network Outage, 10/29

October 29, 2022 by Derek Calderon

Beginning at 8:05 this morning, there is a partial wired network outage on the first floor of Cory Hall. The apparent cause is a failed switch; staff will arrive onsite this afternoon to investigate further and attempt repair.

We do not believe that wi-fi networks, or wired networks on other floors, are affected at this time.

Update 15:45: Network service was restored just prior to 3PM this afternoon. Please email help@eecs.berkeley.edu if you notice continuing network issues.

Soda and Cory Halls Network Maintenance, Thu. 7/14 6AM

July 11, 2022 by Derek Calderon

At 6AM on Thursday, July 14th, we will be performing emergency maintenance in order to address recent network instability. Soda and Cory Hall wired and wireless networks will experience interruptions during this time, and we expect all connectivity will be restored by 7AM. IDSG services in 290 Soda (such as file service) will not be interrupted, but Instructional services in 290 will be interrupted.

BWRC will also be isolated from Campus and the Internet for a period during this maintenance.

Some systems or services such as nfs mounts may need to be restarted after this maintenance. Please contact us at help@eecs.berkeley.edu if you have any questions.
