Upon arrival we confirmed both edge firewalls were up and configuration loading was failing due to no response from the physical fiber uplink. After switching to our backup uplink the issue resolved. We are still diagnosing the issue with the primary fiber uplink but the root cause appears to be an upstream provider uplink and not within our network.

Initial assessment shows that the edge firewall and it's HA counterpart went down at near identical timestamps and upon loading the configuration refuses to deserialize. We are arriving on site to restore a backup to a third firewall device while we quarantine and investigate the two primaries offline. No ETA at the moment
