The New York Stock Exchange halted trading at 11:30 this morning due to a technical glitch. 

“We’re currently experiencing a technical issue that we’re working to resolve as quickly as possible. We will be providing further updates as soon as we can, and are doing our utmost to produce a swift resolution, communicate thoroughly and transparently, and ensure a timely and orderly market re-open,” a NYSE spokesperson said in an email to Fox Business.

Officials say President Obama was briefed on the situation. SEC Chairman Mary Jo White said officials were "monitoring the situation closely."

Trading eventually resumed shortly after 3pm ET.

A DHS official told Fox Business Network that there is no reason to believe this was caused by a cyberattack.

There is currently no timetable for trading to resume, Neil Cavuto reported on FBN. 

Earlier today, United Airlines grounded flights for nearly two hours due to computer problems, blaming a "network connectivity" issue. 

The Wall Street Journal's website also went down briefly, though it appears to be back up and running.

Rudy Giuliani reacted this afternoon on Fox Business, slamming NYSE for failing to plan for a crisis. He said the company "better be right" that this is not being caused by hackers.
