DBS CEO writes to customers personally apologizing for
last week's service disruption
SINGAPORE: DBS Group CEO Piyush Gupta has written to DBS
and POSB customers, personally apologizing for the inconvenience
caused by the sudden disruption in banking and ATM services from 3
am to 10 am on July 5.
In a letter posted on the bank's website, he said
customers have every right to expect uninterrupted services 24/7,
365 days a year from the banking group.
He said he's sorry the group has failed them.
The CEO said it was the first time DBS had experienced a
system outage and service disruption of such magnitude.
Explaining what happened, Mr Gupta said the outage last
week was triggered during a routine repair job on a component
within the disk storage subsystem connected to the
mainframe.
A component replacement was scheduled for 3 am, a quiet
period, which is standard operating procedure.
Unfortunately, while IBM was conducting this routine
replacement, a procedural error inadvertently triggered a
malfunction in the multiple layers of systems redundancies which
led to the outage.
Mr Gupta said he's treating this matter with utmost
priority and the full scale investigation that was initiated last
week is still underway.
This investigation is being done with the support of IBM's
labs in the US and their engineering teams in Asia.
So far, he said DBS understands from IBM that an outdated
procedure was used to carry out the repair.
In short, a procedural error in what was to have been a
routine maintenance operation subsequently caused a complete system
outage.
He said DBS takes full responsibility for this incident
and it's working closely with IBM to ensure that such lapses do not
recur or cause such significant impact.
In fact, he said 12 months ago DBS commenced work on a
major two- year program to further strengthen the resiliency of our
system and minimize the risk of service disruptions.
Mr Gupta also assured customers that all payments and
transactions that were scheduled to be made on July 5 were
completed.
On hindsight, he said DBS' internal escalation process
could have been more immediate.
Mr Gupta said the bank could also have done more to
mobilise broadcast channels to inform customers of the disruption
in services first thing in the morning.
Mr Gupta said there have been valuable lessons learned. -
