North Korea's link to the internet broke on Monday. This came a day after they threatened to bomb the white house over the movie "The Interview"
According to NY Times ;
A Strange thing happened to North Korea’s already tenuous link to the Internet on Monday: It broke.
While perhaps a coincidence, the failure of the country’s computer connections began only hours after President Obama declared Friday that the United States would launch a “proportional response” to what he termed an act of “cybervandalism” against Sony Pictures.
Over the weekend, as North Korean officials demanded a “joint investigation” into the Sony attacks and denied culpability — an assertion the United States rejected — Internet service began to get wobbly.
By early Monday, the Internet went as dark as one of those satellite photographs showing the impoverished country by night.
Experts who monitor the health of the global Internet called it one of the worst North Korean network failures in years. But American officials who had described over the weekend how they were intensely focused on the country’s telecommunications connections through China — and how they had asked the Chinese government for help in cutting off the North’s ability to send malicious code around the world — declined to discuss what befell those connections.
Doug Madory, the director of Internet analysis at Dyn Research, an Internet performance management company, said that North Korean Internet access first became unstable late on Friday. The situation worsened over the weekend, and by Monday, North Korea’s Internet was completely offline.
“Their networks are under duress,”“This is consistent with a DDoS attack on their routers,” he said, referring to a distributed denial of service attack, in which attackers flood a network with traffic until it collapses under the load.
