The NY Stock Exchange was shut down Wednesday by what officials called glitches, the longest shutdown in its history.
Glitches crashed the website of the country's most widely read financial news organization - the Wall Street Journal.
A computer system glitch left thousands of United Airlines passengers across the globe grounded Wednesday, causing a ripple effect of heavy delays.
About 3,500 flights were affected world-wide by the glitch.
A Patriot missile defense battery operated by Germany on the Syrian-Turkish border reportedly received "unexplained commands" from a "foreign source," sparking fears it has been hacked, according to news reports.
It was unclear who or what sent the commands, but government officials are now saying it may have been a glitch, denying outside hacking.
Companies and government officials said the glitches had nothing to do with cyper-attacks, but it has raised fresh questions about the strength of the nation's cyber infrastructure and the heavy reliance on fallible technical systems.
