There is an ongoing investigation into the collapse of DBS Bank's network. It seems now that the performance of the bank was not able to meet reliability standards which have been laid down by the Monetary Authority of Singapore (MAS).

Banks are the major financial supports and therefore they have to continue their services every time.

MAS has highlighted this point in its regulations regarding Internet banking and technology risk management. MAS  has disclosed in the guidelines that customers expect the online banking services to be available '24 hours every day of the year'.

The regulations also say that the banks, their service providers and the retailers  who offer Internet banking should make sure that they have plenty of reserves and capabilities in regard to software, hardware and other working capabilities in order to deliver regularly dependable services.

Therefore, banks are expected to have 99.99% systems availability. The most challenging levels in the fields of technology are imposed on military-grade systems with failure threshold being 32 seconds per year.

But, on Monday DBS experienced its most severe systems up till now. The technical faults interrupted the other customer banking services which included the credit card, Nets payments and automated teller machines.
