Technical Glitch Takes Down New York Stock Exchange

Trading on the floor of the New York Stock Exchange ground to a halt midday Wednesday, as the largest U.S. share venue apparently suffered a technical issue.
The development grabbed a lot of attention, especially because it happened after United Airlines temporarily grounded flights due to a glitch and as the homepage for the Wall Street Journal went down.
While conspiracy theories quickly spread, the NYSE was quick to say hackers weren’t behind the outage.
