Emantra technical staff identified that a Cisco ASA firewall had failed, and an automated fail over was initiated to the hot-spare in the same location. It was later identified that an inconsistent configuration between the active and spare firewall resulted in a partial outage to customers affected by missing whitelist rules due to the inconsistency.

Emantra has identified a process automation error which resulted in the inconsistency and has added additional alerting to identify the inconsistent commit issue which caused this incident.
