Firewall Migrations for Many Networks, 2/22 6AM

by

At 6AM on Tuesday, February 22 at 6AM, we will be migrating a large number of networks to our new border firewall. This will affect the majority of wired networks in Soda, Cory, and Sutardja Dai Halls. EECS-Secure and EECS-PSK in all locations except BWRC will also be affected.

There will be a brief interruption to each of these networks as they are migrated. In addition, the ipv6 subnets used by EECS-Secure and EECS-PSK clients will change. You can read the full post below for details.

We encourage system administrators to test their systems on Tuesday morning after this maintenance is complete, to ensure their applications are being properly handled by the new firewall.

BWRC Network Outage, 2/7

by

BWRC networks are offline since around 13:10 today due to an apparently external cause. Staff are going onsite to investigate.

Update: The issue self-resolved around 13:48, but we believe this to have been an outage of the AT&T circuit which currently serves BWRC. We have plans to move this link to a more stable service later this week.

Network Border Maintenance, 2/7 6AM

by

At 6AM on Monday, Feb. 7, we will be disabling our old/legacy uplinks to the campus network. Our new uplinks were finalized last year and traffic has been using both pairs of links since then. As a result, we expect no impact from this maintenance.

Please contact help@eecs.berkeley.edu if you have any questions or concerns.
