North Korea experiencing widespread Internet outages

North Korea experienced a massive Internet outage Monday, and some researchers and web watchers speculated that the country's online connections could be under cyberattack.

The Internet outage comes less than a week after the U.S. vowed an unspecified response to a massive hacking attack against Sony Pictures Entertainment over the release of the comedy film "The Interview." The plot of the comedy centers on the assassination of North Korean leader Kim Jong Un, leading to widespread speculation that the country was responsible for the attack. Late last week, the FBI publicly blamed North Korea in the incident, though Pyongyang has denied involvement.
