SEBI asks NSE why back up site did not work?

SEBI responding to the trading halt has questioned by India’s largest bourse NSE on why trading did not migrate to the disaster recovery site.  The DR site is a backup site which is located in another city and is a replica of the main production site in Mumbai 

In fact, the National Stock Exchange had informed brokers in October that for two complete trading days, September 28 & 29 the bourse had operated entirely out of the disaster recovery site, notably without any issues.  Ironically the next round of testing is due end of March.

SEBI has sought a complete report including the details of internal assessments which led to the 4-hour trading halt on Wednesday. SEBI however reassured investors that the market regulator would take all necessary measures to ensure rectification of the underlying causes including addressing institutional deficiencies.
