Datacenter Network Firewall Migration

Maintenance Window: 4:00 AM to 8:00 AM Thursday, December 1st
Services Impacted: Many Campus Network and Datacenter Services

During this maintenance window, a campus datacenter firewall will be migrated to new high-capacity, next-generation security system, affecting multiple server and secure workgroup networks. This migration will require multiple brief (few minutes) interruptions to a large number of campus services as systems are transitioned and tested. Interruptions are expected to occur early in this maintenance window, followed by extensive low-impact testing. Longer interruptions in service may be required if unexpected circumstances arise and additional troubleshooting is necessary.

As a precautionary measure during this work, some campus applications will be shut down until the migration is complete, and as such, will experience more prolonged service interruptions. Most notably, the BlackBoard Learn system will be shut down at 4:00 AM, and remain offline until migration activities are complete and uninterrupted service can be assured. All systems and services will be back to normal operation before 8:00 AM.
