This PBS NewsHour segment from late December 2014 captures the immediate fallout of North Korea's sudden internet blackout, coming right on the heels of the infamous Sony Pictures hack. Judy Woodruff sets up the story, highlighting a New York Times report displayed on screen at 00:24 that detailed how North Korea's web traffic went completely dark. She brings in reporter David Sanger, who breaks down just how tiny North Korea's internet footprint actually was at the time—roughly a thousand IP addresses, fewer than what you would find across a few city blocks in Manhattan. Sanger explains that because their global connectivity was restricted to a small ruling class, military leaders, and state propaganda organs, taking their networks down was technically straightforward, whether caused by a targeted cyber attack or an internal outage.
The interview then digs into who might have been behind the collapse and what it accomplished. Woodruff asks whether this blackout represented the proportional response President Obama had promised following the Sony attack. Sanger outlines the geopolitical angles, pointing out that almost all of North Korea's external web traffic flowed directly through China Unicom. He considers whether Chinese authorities severed the link at the request of Washington or due to their own annoyance with Pyongyang, while also weighing other non-cyber sanctions available to the Obama administration, such as freezing elite financial accounts in Macau or placing North Korea back on the list of state sponsors of terrorism.
Looking back at this clip offers a fascinating snapshot of an early milestone in state-sponsored cyber conflict. At the time, the Sony hack and the subsequent blackout felt like uncharted territory, demonstrating how vulnerable a nation's digital presence can be when its entire connection to the outside world hinges on a single upstream provider. Sanger's analysis remains remarkably sharp, highlighting how hard it is to execute effective cyber retaliation against an isolated country that barely uses the internet in the first place.
