At approximately 22:12 UTC internal monitoring detected a disruption in service from our East Coast data center. Investigation determined it to be related to internal database issues. All traffic was re-0directed to our west coast data center. The issue was resolved at approximately 23:15 UTC.
A connectivity failure between the east and west coast data centers disrupted database replication. This disruption caused a loss of appliance licensing data, which resulted in some appliances being treated as unlicensed, which impaired all functions of the impacted appliances.
The immediate problem was resolved by a database restore and manual data merge. Subsequently, the communications failure was identified as a mismatch between load balancer and firewall rules, which has been corrected. Our active test and monitor tools are being extended to monitor the load balancer - firewall communication channel to provide earlier detection and quicker identification of this class of issue.
