On Wednesday, the United States faced multiple problems in the operation of computer systems.

Wednesday was a hard day for computer security specialists. For some unknown reason, the work on the New York Stock Exchange was simultaneously suspended , one of the largest airlines in the United States and the whole world, United Airlines, suspended all flights , and the website of the venerable publication The Wall Street Journal gave an error 504.

The problems of the journal were eliminated in a couple of hours - first, all users were redirected to a temporary site, and then they restored the work of the main one. The airline also coped with its problems, saying that the whole reason was a stupid router that interrupted the company's internal network. Due to an error, 59 flights were canceled and over 1200 were delayed.

The stock exchange did not recover so quickly, and resumed trading only after four hours of complete inactivity . At this time, in order to avoid confusion, the press service of the White House, the Department of Homeland Security and the exchange itself released messages stating that the accident was not caused by any attacks , but was only the consequences of installing a software update.

As a result of the failure on the exchange, it was necessary to manually cancel all orders placed before the break in work, of which more than 700,000 had accumulated.

The only strange thing is that 12 hours before the commencement of the commotion, on Tuesday evening, the hacker group Anonymous on its twitter in an ironic manner expressed the hope that the next day would not be bad for Wall Street.



At the end of the commotion, the hackers successfully congratulated themselves on the prediction.
