October 14, 2016: Datacenter Network Firewall Migration

Maintenance Window: 4:00 AM to 8:00 AM Friday, October 14th
Services Impacted: All Campus Network Services

During this maintenance window, campus datacenter firewalls will be migrated to new high-capacity, next-generation security systems. This migration will require multiple brief (few minutes) interruptions to all campus network 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 4:00AM, and remain offline until migration activities are complete and uninterrupted service can be assured.

Potential update for Collaborate B2

If time allows, DLT may use this maintenance window to install an updated Blackboard Collaborate B2.
