“North Korea, at the center of a confrontation with the United States over the hacking of Sony Pictures, experienced a complete Internet outage for hours before links were restored on Tuesday, but U.S. officials said Washington was not involved. U.S.-based Dyn, a company that monitors Internet infrastructure, said the reason for the outage was not known but could range from technological glitches to a hacking attack. Several U.S. officials close to the investigations of the attack on Sony Pictures said the U.S. government had not taken any cyber action against Pyongyang.”
