Trading on the National Stock Exchange resumed on Wednesday evening after it was halted due to a technical glitch. The snag had stopped the updating of live price quotes of Nifty and Nifty Bank indices around 11.40 am. Later, the market closing time was revised to 5 pm, instead of the normal 3.30 pm.

Around noon on Wednesday, the exchange had said that trading was halted due to a glitch with its telecom service providers.

“NSE [National Stock Exchange] has multiple telecom links with two service providers to ensure redundancy,” the NSE tweeted. “We have received communication from both the telecom service providers that there are issues with their links due to which there is an impact on NSE system.”
