Researchers Wenbin Wu and Alexander Neumueller from the Cambridge Centre for Alternative Finance published a study in February, revised on March 12, testing the resilience of the Bitcoin network. The failure of approximately three-quarters of submarine fiber optic cables carrying 99% of international internet traffic has no significant impact on the BTC network.

BTC Network Critical Threshold in Random Cable Failures
In random cable cuts, the critical threshold that disrupts network functionality is between 72-92%. This demonstrates the strength of Bitcoin’s P2P architecture, as we emphasized on our BTC detailed analysis pages. The modeling simulates connection failures to calculate node isolation.
BTC Node Loss Risk in Targeted Attacks
In attacks targeting specific bottlenecks, the threshold drops to 5-20%; more than 10% of the network’s nodes go offline. This scenario is critical in geopolitical risks (e.g., Hormuz Strait cables). The researchers identified these weak points using gradient boosting models.
Bitcoin Study’s Methodology and Data
Country-level stepwise modeling was conducted using 2014-2025 P2P network data and 68 verified cable failures. This is BTC’s first long-term submarine cable resilience analysis. 87% of the 68 failures impacted nodes by less than 5%.
| Failure Type | Affected Node Ratio | Number of Incidents |
|---|---|---|
| Low Impact (<5%) | 87% | 59 |
| Medium Impact (5-10%) | 10% | 7 |
| High Impact (>10%) | 3% | 2 |
Tor Usage Increases BTC Resilience
64% of BTC nodes operate covertly via Tor; the relay infrastructure is concentrated in countries with strong connectivity like Germany, France, and the Netherlands. Resilience increases over time with Tor adoption, a factor reducing volatility in BTC futures.

Correlation Between Cable Failures and BTC Price
Correlation between cable events and BTC price is close to zero (-0.02). The geographical distribution of mining does not affect the physical cable topology. Current BTC price $73,757.84 (+2.97%), RSI 59.89 (neutral), sideways trend with Supertrend giving bearish signal.
| Support | Price | Score |
|---|---|---|
| S1 | $72,829.72 | 60/100 ⭐ |
| S2 | $69,230.02 | 58/100 |
| Resistance | Price | Score |
|---|---|---|
| R1 | $74,469.09 | 85/100 ⭐ |
| R2 | $76,852.37 | 66/100 ⭐ |
Strategic Recommendations for BTC Investors
This analysis confirms BTC’s maturity against infrastructure shocks. Investors should monitor the R1 resistance in the BTC spot market; running a Tor-based node personalizes resilience.
