Largest stock bourse NSE on Thursday said the unavailability of an ‘online risk management system’ led to the nearly four hour shutdown of trading on Wednesday.
It is also awaiting a detailed root cause analysis from its telecom service providers and vendors regarding the incident, the exchange said.
Explaining the series of events leading to the shutting down of trading, the NSE said it has multiple telecom links with two service providers to ensure redundancy and the two telcos informed it about “instability of all their links”, as per a statement.
