When Submarine Cables Go Dark: Understanding and Preparing for the Risks of Taiwan's International Internet Disconnection

A research study analyzes how 2,179 commonly-used Taiwan websites depend on foreign infrastructure, finding that 39.3% rely directly on foreign-hosted resources and 49.6% depend on multinational cloud/CDN nodes in Taiwan. The paper introduces a measurement framework to quantify internet dependency risks during submarine cable outages, providing concrete data on which websites face higher failure risk if international connectivity is severed.

Background

Taiwan's internet connectivity relies heavily on submarine cables crossing the Taiwan Strait, creating vulnerability to physical disruption. This research is part of broader efforts by organizations like the Open Culture Foundation to assess and improve regional internet resilience.
