February 22, 2022 by Derek Calderon

Cory Hall 2nd Floor networks went offline this afternoon, 2/22, at 12:51PM due to a malfunctioning switch. The switch was restored remotely and wired networking returned at 1:13PM. Wireless networking has not yet fully recovered and we are working on this.

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.

Network Border Maintenance, 2/7 6AM
