The FBI accused the North Korean government last week of perpetrating the devastating cyberattacks against Sony’s computer network for which a group calling itself the Guardians of Peace took responsibility. The North Korean government denied the charge and warned of serious consequences if the United States launched any counter-attack. President Obama ignored the threat, declaring that the U.S. would respond “proportionally” to what he characterized as cyberspace “vandalism.”
This Monday, North Korea experienced a total Internet outage for a bit less than ten hours. “I haven’t seen such a steady beat of routing instability and outages in KP before,” Doug Madory, director of Internet analysis at DYN Research, told North Korea Tech, referring to North Korea’s Internet country code top-level domain. “Usually there are isolated blips, not continuous connectivity problems. I wouldn’t be surprised if they are absorbing some sort of attack presently.”
North Korea’s Internet access, which it obtains through China-based facilities, has since been restored.
Some observers have attributed the temporary Internet outage to the fulfillment, in part or in whole, of Obama’s “proportional” response, which a White House National Security spokeswoman would neither confirm nor deny. Whether China may have played a role in the temporary outage is unknown, but doubtful.
