Customers of DBS Bank and Citibank faced difficulties accessing their banking and payment services on Oct. 14.

According to a spokesperson from the Monetary Authority of Singapore (MAS), the banks informed the agency about the service disruptions in the afternoon.

Preliminary investigations indicate that the service disruptions were caused by an issue at a common data centre that is used by both banks, the MAS spokesperson said.

The spokesperson also added that MAS has been following up closely with the banks, as they worked towards a full resumption of their services and provide timely communications and support to affected customers.
