India’s two national equity bourses in a rare move extended trading hours for Wednesday after the National Stock Exchange of India Ltd. had to shut its cash and derivative segments due to “issues” with telecom links of its two service providers.

The joint decision came after the NSE, the world’s biggest derivatives exchange by number of contracts, halted trading for more than three hours in what was its longest-ever outage. Marker regulator Securities and Exchange Board of India has asked the exchange to carry out a detailed root-cause analysis of the halt and explain why trading didn’t migrate to its disaster recovery site.
