[Cambridge Study: Bitcoin Can Withstand Global Submarine Cable Failures Below 72%, But Targeted Attacks on Top Five Hosting Providers Could Cripple the Network] Deep Tide TechFlow reports that on March 14, according to CoinDesk, the Cambridge Centre for Alternative Finance released a longitudinal study on the physical infrastructure resilience of the Bitcoin network, covering 11 years of peer-to-peer network data and 68 verified submarine cable failure incidents. The study shows that 72% to 92% of global transnational submarine cables would need to fail simultaneously for the Bitcoin network to experience significant node disconnection. Based on 1,000 Monte Carlo simulations per scenario, over 87% of real failure incidents impacted nodes by less than 5%, and the correlation coefficient between cable failures and Bitcoin price was close to zero (-0.02). The study also revealed a significant asymmetry between random failures and targeted attacks: if attackers target critical hub cables, the disruption threshold would sharply drop to 20%. If targeted attacks were directed at the top five hosting providers with the highest number of nodes—Hetzner, OVH, Comcast, Amazon, and Google Cloud—removing just 5% of routing capacity could cause equivalent disruption.
