NYSE, United Arlines, WSJ Website Back to Business After Technical Glitches
It's back to business this morning after a series of technical glitches grounded thousands of United Airlines flights, halted trading on the floor of the New York Stock Exchange and brought down the Wall Street Journal's website.
United Airlines says a router knocked several systems offline.
The New York Stock Exchange also resumes trading after a glitch stopped trading for nearly four hours Wednesday.
They blame the incident on a configuration issue.
Both incidents came on the same day another technical issue brought down the Wall Street Journal's website.
Some lawmakers on Capitol Hill question whether the outages were just caused by computer issues.
They call for the Obama administration to take more actions to step up cyber security, arguing fragile technology networks could make businesses vulnerable.
