Computer "Glitches" Shut Down New York Stock Exchange, United Airlines, WSJ

CNN reports:

The New York Stock Exchange suspended trading 11:32 a.m ET Wednesday. In a brief announcement, the exchange said it was experiencing a "internal technical issue" and said on Twitter that it's "not the result of a cyber breach." "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," the NYSE said. The Department of Homeland Security told CNN that there is "no sign of malicious activity" at the NYSE or with an earlier outage experienced by United Airlines. The Wall Street Journal's homepage stopped functioning around the same time that the NYSE went down. The Journal was able to restore a limited homepage by 12:18 pm ET with the message "WSJ.com is having technical difficulties. The full site will return shortly."

More about United:

United Airlines said on Wednesday it was restoring operations after all its flights were grounded for about two hours due to computer problems. Earlier, the Federal Aviation Administration grounded all of United's flights following a systemwide computer glitch, which was resolved, the agency said. The grounding order began at 8 a.m. EDT and ended at 9:47 a.m. About 260 flights were delayed, or 12 percent of all United flights, according to website FlightAware, while seven flights canceled. United in a statement said "We are recovering from a network connectivity issue this morning and restoring regular flight operations." United said it would rebook flights for affected passengers without charge.
