North Korea experienced a brief but significant disruption to its internet routing infrastructure on Tuesday. The event, which lasted approximately 15 minutes, was characterized by a sharp drop in Border Gateway Protocol (BGP) visibility.
Technical Details
The disruption occurred between 15:05 and 15:20 UTC on August 11. The event registered a severity score of 205, with the primary impact observed on the BGP control plane signal. BGP visibility dropped by 18% from its peak during the event window.
The BGP signal measures the stability and visibility of routing announcements for a country’s IP address prefixes on the global internet. A concurrent, smaller degradation was also recorded in the ping-slash24 signal, which measures ICMP reachability to active IPv4 network blocks, showing a 50% drop from its peak.
The cause has not been publicly attributed.
Connectivity was reported restored following the brief event.
