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.
