India’s stock market, like its peers across the world, is no stranger to sudden trading halts due to technical glitches. On Thursday, India’s second-biggest exchange operator BSE halted trading across all its segments due to a network outage. Trading on the NSE bourse was not affected.

The three-hour outage was the longest in recent memory and follows three earlier outages in a year that has seen stocks scale fresh peaks on expectations of economic revival from a new government.

The BSE, Asia’s oldest stock exchange, has more than 5,000 listed companies. Data from the World Federation of Exchanges shows shares worth $85 trillion were traded on the BSE last year, compared to $479 trillion for the NSE, India’s leading stock exchange.

Here’s a list of glitches faced by India’s stock market exchanges over the past few years:

*July 3, 2014: The BSE resumed trading after a three-hour network outage that is being investigated. Preliminary reports will be sent to stock market regulator SEBI and the finance ministry. The trading disruption was the longest suffered by the BSE since at least 2010, a spokesman said.
