SEOUL, South Korea (AP) — Key North Korean websites were back online 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.
It wasn't immediately clear what caused the Internet stoppage in one of the least-wired and poorest countries in the world, but outside experts said it could be anything from a cyberattack to a simple power failure. The White House and the State Department declined to say whether the U.S. government was responsible.
Even if a cyberattack had caused the shutdown, analysts said, it would largely be symbolic since only a tiny number of North Koreans are allowed on the Internet — a fraction of Pyongyang's staunchly loyal elite, as well as foreigners.
Though it denies responsibility for the Sony hack, North Korea's government has called it a "righteous deed" and made clear its fury over Sony's film "The Interview," a comedy that depicts the assassination of the North's authoritarian leader, Kim Jong Un, the head of a 1.2 million-man army and the focus of an intense cult of personality.
South Korean officials, speaking on condition of anonymity because of office rules, said the North's official Korean Central News Agency and the Rodong Sinmun newspaper, which are the main channels for official North Korean news, had both gone down. But the websites were back up later Tuesday. Among the posts glorifying the ruling Kim family included one about Kim Jong Un visiting a catfish farm.
U.S. computer experts described the 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.
Possible causes for the shutdown include an external attack on its fragile network or even just power problems, Cowie wrote. But, he added, "We can only guess."
