ROOT CAUSE ANALYSIS
Cause:
The service outage was due to a crash on Firewall 1. Firewall 2, the back redundant node, took over thus just causing a quick blink.
Resolution:
The redundant firewall took over traffic preventing a long term outage.
Prevention:
We had Firewall redundancy in place. Once Firewall 2 took over all internet services came back online. All Firewalls are back up and redundancy is back in place.
Engineers will be monitoring and working with Palo Alto support, on why this crash occurred to find out root cause?
