Almost 9 out of 10 underwater web cable failures over the previous decade precipitated little to no disruption to the Bitcoin community, based on new educational analysis.
Random Failures Vs. Targeted Cuts
The study, revealed in February by researchers Wenbin Wu and Alexander Neumueller of the Cambridge Centre for Alternative Finance, tracked 68 confirmed cable fault occasions between 2014 and 2025.
Data reveals 87% of these incidents knocked fewer than 5% of Bitcoin nodes offline. Price impression was primarily nonexistent — the correlation coefficient between cable failures and Bitcoin’s market worth got here in at -0.02, a determine researchers describe as statistically insignificant.
The examine is the primary of its variety to have a look at Bitcoin’s publicity to bodily web infrastructure over a protracted stretch of time.

Using a country-level cascade mannequin constructed on peer-to-peer community knowledge, the researchers got down to reply a query that has circled the crypto group for years: what would truly occur to Bitcoin if the web took a severe hit?
Their reply, at the least for random failures, is: not a lot. Between 72% and 92% of all submarine cables connecting international locations worldwide must fail earlier than greater than 10% of Bitcoin nodes go darkish.
Subsea cables carry roughly 99% of worldwide web site visitors. Getting to that failure threshold would require a catastrophic, near-total collapse of worldwide web infrastructure.But the image modifications sharply when the failure is deliberate.

Chokepoints Present A Different Problem
Targeted assaults on particular cable chokepoints may obtain severe disruption with far fewer cuts. Officials stated researchers discovered the crucial failure threshold drops to between 5% and 20% when assaults are aimed toward high-traffic junction factors — a risk the paper describes as roughly an order of magnitude stronger than random failures.
That hole between random and focused threat is the sharpest discovering within the report. It suggests Bitcoin’s publicity to bodily infrastructure isn’t evenly distributed.

Geographic range in Bitcoin mining, which expanded considerably after China’s 2021 crackdown pushed operations to different international locations, has carried out little to alter this image.
Reports point out that infrastructure energy tracks bodily cable routes, not the place miners occur to be positioned.
Tor Adds A Layer Of Complexity
One issue working in Bitcoin’s favor is the widespread use of Tor, the privacy-focused routing system that bounces site visitors by way of a series of servers to masks a consumer’s location.
Based on studies, 64% of all Bitcoin nodes are successfully invisible to outdoors observers due to Tor adoption — a element that complicates any effort to map and goal the community.
