North Korea goes totally offline for hours; reason unknown

Seoul

NORTH Korea, which is at the centre of a confrontation with the US over the hacking of Sony Pictures, experienced a complete Internet outage for hours before links were restored on Tuesday, but US officials said Washington was not involved.

US-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 US officials close to the investigations of the attack on Sony Pictures said the US government had not taken any cyber action against Pyongyang.
