NYSE Euronext says software upgrade caused 30 minute shutdown

NEW YORK, Sept. 16 (UPI) -- NYSE Euronext said a software upgrade uploaded over the weekend caused a 30-minute outage in trading in New York on Monday.

Problems arose with the Options Price Reporting Authority, which the exchange oversees. With the unexpected glitch, the data system had difficulty processing options quotes, The Financial Times reported. That triggered a shutdown that lasted about 30 minutes Monday afternoon.

A 3-hour outage of the Nasdaq exchange in August prompted the U.S. Securities and Exchange Commission to call a meeting of U.S. exchange operators, which took place last week.

The meeting was held to discuss options for avoiding outages, such as the one that occurred Monday, the Financial Times said.
