The Singapore banking industry witnessed one of the biggest failures in its history last week. DBS Bank’s storage system, which is managed by IBM staff and solutions, was inaccessible for seven hours.
The problem started with a false-Negative alarm by the monitoring system. The monitoring system detected “instability” within DBS Bank’s storage system. With reference to IBM’s statement at networksasia.net the system was “fully functional” but IBM employees initiated a recovery process to fix the issue.
This recovery process took seven hours and made the bank’s customers unable to access their accounts and DBS Bank’s departments were non-functional.
IT professionals should consider this incident, and the incidents like BP valves on the coast of Mexico, as warnings. Business continuity and disaster recovery plans need to be exercised, and tested frequently. Otherwise, they are just documents which are not useful in a time of disaster.
