Resolved after 5 minutes, affecting Breezemail.ai and Office365 Inbox Protection Manager and 1 more, on March 6, 2026.

The failover temporarily interrupted network traffic while the secondary node assumed the master role. Root Cause The demotion was triggered by firewall link-state monitoring safety mechanism . Evidence indicates the link-state flap was likely caused by hardware-layer issues: Resolution High Availability (HA) functioned as designed: The secondary firewall automatically took over as the CARP master Network services were restored once failover completed Total impact time was approximately 6 minutes
