DBS Bank Service Outages: A Case Study and Lessons for Online Businesses
In a decisive move, the Monetary Authority of Singapore (MAS) has imposed a six-month moratorium on DBS Bank's acquisition of new business ventures and non-essential IT changes. This action comes in response to a series of service disruptions that have plagued Singapore's largest lender throughout the year, culminating in a significant incident on October 14, 2023, linked to a cooling system failure at a data center. The MAS's directive aims to ensure that DBS dedicates the necessary resources to fortify its technology risk management and operational resilience.
Timeline of DBS Bank Outages
DBS Bank experienced major disruptions to its banking services this year - on 29 March, 5 May, 26 September, 14 and 20 October 2023.
March 2023: A day-long outage affects online banking and payment platforms, leading to a public reprimand from MAS.
May 2023: Digital banking services and ATMs go down due to a coding error during system maintenance.
October 14, 2023: A technical issue at a data center disrupts digital banking and payment services for several hours, also impacting ATMs and necessitating the reopening of branches on a weekend.
These incidents have prompted a comprehensive review by MAS and the implementation of a phased remediation plan by DBS, expected to take up to 24 months. The bank has also been directed to maintain its current branch and ATM network to provide customers with alternative service channels during this period.
