North Korea's Internet and 3G mobile networks went down again on Saturday evening, China's official Xinhua news agency reported, hours after the North Korean government called Obama a "monkey" and blamed the U.S. for enduring instability in the country's Internet infrastructure. Internet connectivity hadn't returned to normal as of 9:30 p.m. local time (7:30 a.m. ET), Xinhua said. On Saturday, the White House refused to deny North Korea's accusations that the U.S. shut down the hermit nation's Internet in retaliation for its alleged hacking attack over the movie "The Interview," with an administration official saying the claim wasn't worthy of an answer.
