North Korean Websites Suffer Additional Outages After Shutdown

The White
House and the State Department declined to say whether the U.S. government was responsible

(SEOUL, South Korea) — Key North Korean websites suffered intermittent outages Tuesday after a nearly 10-hour shutdown that followed a U.S. vow to respond to a crippling cyberattack on Sony Pictures that Washington blames on Pyongyang.

              

U.S. computer experts described Monday’s Internet outage in the North as sweeping and progressively worse. Jim Cowie, chief scientist at Dyn Research, an Internet performance company, said in an online post that the North came back online after a 9 ½-hour outage. But the company said the North later suffered two outages, one lasting half an hour.
