TLDR
Anchor risk on hosting-provider concentration, not submarine cables: the Cambridge 11-year study via CoinDesk finds Bitcoin can route around up to ~72% of global cable cuts but is vulnerable if five major hosting providers are simultaneously disrupted.
Why this matters
Infrastructure asymmetry: Diverse cable paths and Tor adoption bolster network connectivity, but reliance on a handful of hosting providers introduces a chokepoint distinct from physical cable risk. Assessment: Bitcoin’s near-term operational resilience is stronger against broad, untargeted physical failures than agai…
What changed
- CoinDesk reports Cambridge research spanning 11 years and 68 verified submarine-cable failures: Bitcoin could withstand cuts to roughly 72% of global cables due to routing and Tor usage gains.
- The same analysis flags a concentrated hosting layer: a targeted disruption of five major hosting providers could materially impair Bitcoin service availability.
- No new primary signals from SEC, DTCC/NSCC, ETF sponsors, or tagged custodian flows since the prior briefing to attribute BTC $70k to ETF creations or redemptions [sources reviewed show none].

Summary
A new Cambridge-analyzed, 11-year dataset reported by CoinDesk indicates Bitcoin is highly resilient to widespread submarine cable failures but could face disruption from a concentrated set of five hosting providers, while there are still no primary ETF or custodian confirmations that would change flow attribution for BTC above $70k since the last briefing.
