Jacobs and HMMB Firewall Migrations, 3/7 6AM

March 1, 2022 by Derek Calderon

At 6AM on Monday, March 7, we will be migrating these wired networks to our new border firewall:

169.229.62.0/24 (Jacobs Hall)
169.229.63.0/25 (BiD Lab in HMMB)

There will be a brief interruption to these networks as they are migrated. After the migration, we encourage system administrators to test that traffic across the firewall is behaving as expected.

Please contact us at help@eecs.berkeley.edu with any questions or concerns.

EECS Network Maintenance, 2/25 6AM

February 24, 2022 by Derek Calderon

Tomorrow morning, 2/25 at 6AM, we will be rebooting the Soda Hall core router in order to apply a configuration change which will resolve an issue currently affecting a small portion of network traffic. As a result, we expect most EECS network paths will be unavailable for up to 15 minutes beginning at 6AM. Some systems or services (e.g. nfs) may have connectivity issues and may need to be restarted or rebooted after this maintenance.

Issues with RFC1918 Networks

February 22, 2022 by Derek Calderon

There is currently no DHCP or DNS service on the RFC1918 networks (10.x.x.x) as a result of this morning’s maintenance. This is primarily affecting printers in Soda, Cory and Sutardja Dai Halls. We are working on a fix and plan to deploy it this evening.

Firewall Migrations for Many Networks, 2/22 6AM

February 15, 2022 by Derek Calderon

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

February 7, 2022 by Derek Calderon

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.
