Maintenance: Restore & Upgrade of Agg1 Firewall Cluster Jun 21, 2025 19:00-21:00 PDT

ITS has scheduled the following maintenance:

WHEN: Saturday, June 21, 2025 1900-2100

IMPACT: ITS Security will be performing a backup and restore operation to resolve a synchronization issue that appeared as a result of the recent failed cluster rebuild of the firewall cluster. This will involve a required simultaneous reboot of both firewalls in the cluster which will result in a 15 minute downtime. During the duration of this reboot there will be an outage for any network firewalled on agg1 to include networks in Nodes M, Muir, U, V, J, A, and K. This also includes RESNET and an outage of the campus NAT and Proxy services. This means wireless, VPN, and RESNET access off campus will also be down.

After the reboot, a firmware upgrade will be performed to bring the cluster up to 7.2.11. During this upgrade process the network will stay up, but users will experience 10-15 small network interruptions as upgrades are done.

Please contact ITS Service Desk at (858)246-HELP(4357) or servicedesk@ucsd.edu if you have any questions or concerns.
