NEW YORK (CBSNewYork/AP) — The New York Stock Exchange resumed trading Wednesday afternoon, after a technical glitch caused an outage for 3 1/2 hours.

Officials said there was a major technical problem around 11:32 a.m. with the NYSE system, CBS News business analyst Jill Schlesinger reported. Trading was restarted at 3:10 p.m.

The outage came just two hours after the opening bell, and the NYSE trading floor went quiet. CBS2’s Alice Gainer reported.

“Waiting — it’s a waiting game for us,” said NYSE trader Michael Mozian. “I mean. we’re not allowed to accept orders.”

The New York Stock Exchange posted on Twitter the problem was an internal technical issue and not the result of a cyberattack. The stock exchange also said it elected to suspend trading to avoid other problems.

“There was a change in some coding — the software that runs some of the systems — and the exchange began to notice that reports and other information were not going out properly, and they shut down the system,” Art Cashin, UBS’ director of floor operations at the stock exchange, told 1010 WINS’ Carol D’Auria.

The Nasdaq and all other exchanges were not impacted, and the halt did not stop trading of NYSE-listed shares altogether.

“Physically on the trading floor, you know, it’s a problem, but it’s not — it doesn’t prevent people from doing what they need to do,” said Ted Weisberg of the Seaport Securities Commission.
