NEW: A new 11 year study analyzing Bitcoin’s resilience to submarine cable failures finds the network remains highly robust even when critical internet infrastructure is disrupted.

Using data from 2014 to 2025 and 68 verified cable fault events, researchers found random cable failures would require roughly 72% to 92% of inter country connections to fail before causing major node disconnection.

Targeted attacks are more effective but still require 5% to 20% of key connections to be disrupted.

The study also found Tor usage increases Bitcoin’s resilience because relay bandwidth is concentrated in well connected regions.

Empirical results show 87% of historical cable faults caused less than 5% node impact.
