Change Summary

Replace the campus perimeter firewall pair (FW-EDGE-01 / FW-EDGE-02) with Palo Alto PA-5440 units to increase throughput from 10 Gbps to 40 Gbps and add inline decryption capacity for TLS 1.3 inspection.

Change Type: Emergency (reclassified from Standard after vendor advisory) Risk Level: High Rollback Available: Yes (old firewalls kept cabled in standby rack positions)

Cancellation Reason

Hardware delivery delayed by vendor logistics issues. New PA-5440 units now estimated to arrive mid-May. Change will be re-submitted with a revised implementation window once hardware is on-site and burn-in tested.
