This island bank is located on the Pacific Rim Ring of Fire and lost its data center for several hours during an earthquake. The bank initiated its disaster recovery plan, but could not bring its backup systems into operation and suffered a failover fault. The most critical outages were its online banking services and its ATM/POS network, which were further aggravated by the production system losing power and having the IT staff evacuated from the primary data center due to concerns about structural damage. The bank addressed these issues by implementing HPE Shadowbase data replication, moving its architecture in a controlled fashion towards an active/active configuration and continuous availability.
