In the aftermath of a significant service disruption on October 14, DBS Group (OTC: DBSDY ) Holdings Ltd and Citigroup Inc (NYSE: C ). are taking measures to enhance their technology risk management systems and controls. The incident saw roughly 810,000 failed attempts by customers to access the banks' digital platforms, and approximately 2.5 million incomplete payment and ATM transactions in Singapore. The service outage was pointed out by Alvin Tan, Minister of State for Trade and Industry, in Parliament. He criticized both banks for not meeting the Monetary Authority of Singapore's (MAS) IT system resilience standards. Despite conducting annual recovery tests at backup data centers, these tests failed to identify the issues that led to the disruption. In response to the incident, DBS extended its branch hours to assist affected customers. The minister emphasized that banks are directly accountable to their customers, with compensation matters being resolved directly between them.
