The New York Stock Exchange shuts down entirely as a "technical issue" bogs the system. While it's been suggested by the NYSE that this is not due to any sort of malicious attack, no definitive answer has yet been given for what the technical bug could be. Word from the chairwoman of the Securities and Exchange Commission Mary Jo White says "We are in contact with N.Y.S.E. and are closely monitoring the situation and trading in N.Y.S.E.-listed stocks." This is the second of two issues today, the first having been announced as resolved at 9:37 AM Eastern Standard Time.
