With a rather suspicious coincidence, North Korea is currently facing a widespread interruption Internet, according to the Associated Press. Connection problems started about 24 hours ago, and have worsened even further since.
If you have not followed the latest events, North Korea has recently been accused by the United States of the recent catastrophic Sony hack. During a press conference, President Obama promised that the United States would "respond accordingly."
Of course, there is no specific indication linking the blackout to Internet North Korea with the United States and the reprisals promised by the country's president.
It could just be an irrelevant interruption in a country that already has limited Internet access. (Keep at least the pretensions if the President has stated that the US has nothing to do with the blackout)
The White House, for its part, refused to comment on the Associated Press's publication.
