IBM error triggers bank outage

DBS Bank has claimed a seven-hour service outage was the result of an error by the IT vendor

DBS Bank says a failure on IBM's part to correctly fix an identified instability within the bank's storage system led to the seven-hour service outage on 5 July.

In a statement posted on its website addressing its customers, DBS chief executive Piyush Gupta said IBM was carrying out "a routine repair job" to address alert messages that indicated a problem with a component in the disk storage subsystem, which was connected to the bank's mainframe.

The IT vendor's Asia-Pacific team was scheduled to replace the component during off-peak hours, specifically 3am, but an error in how the fix was applied triggered a malfunction in the bank's redundancy systems, leading to the outage.
