Outage category: Telephone, VoIP phone service, VPN, Webex, Wired Network, Wireless Network
Location: All Campuses
Status: Closed
Resolved Alert:
Initial Symptoms
Network Connectivity dropped.
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?
