Just published: first study of Bitcoin's resilience to submarine cable failures, using 11 years of P2P network data & 68 cable fault events. Random cable failures are mostly harmless, but targeted attacks on 5 hosting providers could take out 95% of clearnet nodes. Authors recommend using tor to increase network robustness.
