  • The post explores the physical layout of North Korea's internet and fiber optic network, based on limited information and assumptions.
  • Key findings include fiber optic connections from Russia and China, with routes likely following major roads and railways, especially along the east coast.
  • Historical data reveals early fiber installations between major cities like Pyongyang, Hamhung, and Sinuiju, with a backbone capacity of 2.5 GB per second for the Kwangmyong intranet.
  • The Kwangmyong network connects all provinces in North Korea, serving as the primary intranet for citizens without access to the global internet.
  • Evidence suggests fiber infrastructure is buried underground, with junction boxes and conduits along railways and highways.
  • Traceroute data indicates different latency patterns for traffic entering North Korea via China versus Russia, hinting at possible centralized routing in Pyongyang or border-proximate hosting.
  • The post invites further information or corrections, emphasizing the speculative nature of the findings.
