Subsea internet cables form the backbone of global digital connectivity, yet they remain surprisingly vulnerable to multiple threat vectors. A new publication examines the full history of underwater cable infrastructure and exposes three critical vulnerability dimensions: physical damage from natural disasters and human interference, geopolitical tensions that could disrupt data flows across regions, and commercial disputes that threaten service continuity. For the crypto and Web3 ecosystem, these cable vulnerabilities raise important questions about network resilience and asset security during infrastructure disruptions.
