North Korea has faced massive Internet outage following allegations that the country was involved in the recent hacking of Sony Pictures.
According to Doug Madory, the director of Internet analysis at US-based cyber security firm Dyn Research, the connection woes emerged over the weekend and grew increasingly worse to the point that “North Korea’s totally down.”
He said that a router might have suffered a software glitch, leading to the problem, though a cyber-attack involving North Korea’s Internet service might also be the reason.
Routing instabilities are prevalent, but this outage in North Korea has lasted for hours and is deteriorating, Madory said.
“This doesn’t fit that profile,” of an ordinary routing trouble, he said. “This shows something getting progressively worse over time.”
In North Korea, Internet access is only available through special authorization and is primarily used for governmental purposes.
The hacking of Sony Pictures, which has been described as the most devastating cyber attack on a US business, has paralyzed the company and led to the cancelation of the screening of a controversial movie, The Interview, which depicts a fictional US assassination plot against North Korean leader Kim Jong-un.
In a statement released on Friday, the US Federal Bureau of Investigation (FBI) said it possessed evidence that Pyongyang was behind the hacking.
North Korea not only denied the accusation, but also proposed a joint investigation with Washington into the cyber-attack against the Sony Pictures’ computer systems.
The country has also warned it will take retaliatory measures if the US imposes sanctions against Pyongyang over hacking claims.
US President Barack Obama has said the US government would respond to the hacking, which he described as an act of “cyber vandalism.”
