This podcast investigates the vulnerabilities of the global undersea cable network, which carries over 95% of internet traffic. The discussion is structured around four parts: the history and physical nature of the cables, the ownership and regulation of the network, the various threats (accidental damage, sabotage, and geopolitical tensions), and potential solutions (improved monitoring, diversification of technologies, and international cooperation). A key concern is the potential for sabotage, particularly in areas like the Baltic Sea and the South China Sea, and the difficulty in attributing responsibility. The podcast concludes that while the network faces significant challenges, its importance to global communication makes it essential to improve its resilience and security.
