North Korea's Internet Access Is "Toast"

Even if the US had something to do with this, the government would probably never admit it, but I think it's doubtful. North Korea's network is very small by world standards, and it wouldn't require a nation state to take it offline with a simple brute force DDoS attack; it seems more like something Anonymous would do: Attack Is Suspected as North Korean Internet Collapses.

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 Friday. The situation worsened over the weekend, and by Monday, North Korea's Internet was completely offline.

"Their networks are under duress," Mr. Madory said. "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.

North Korea does very little commercial or government business over the Internet. The country officially has 1,024 Internet protocol addresses, though the actual number may be somewhat higher. By comparison, the United States has billions of addresses.

CloudFlare, an Internet company based in San Francisco, confirmed Monday that North Korea's Internet access was "toast." A large number of connections had been withdrawn, "showing that the North Korean network has gone away," Matthew Prince, CloudFlare's founder, wrote in an email.

Although the failure might have been caused by maintenance problems, Mr. Madory and others said that such problems most likely would not have caused such a prolonged, widespread loss.
