Internet disruptions in Kazakhstan, the world's second-biggest bitcoin mining hub, shut down an estimated 15% of the world's miners before internet was restored
> Kazakhstan's deadly protests hit bitcoin, as the world's second-biggest mining hub shuts down https://www.cnbc.com/... Heidi Cuda / @heidi_cuda : “Kazakhstan's deadly protests hit bitcoin, as the world's second-biggest mining hub shuts down... Bitcoin fell below $43,000 for the first time since September in trade on Thursday, falling over 8% at one point.” https://www.cnbc.com/... @CNBC cc @davetroy courtesy of HiFi Random Facts Girl / @soychicka : Kazakhstan is home to 0.24% of the world's population, but 12% of bitcoin mining? $1.8Bn is > 1% of the total Kazakh GDP (though I doubt it's properly reported and taxed). https://fortune.com/... Julian Oliver / @julian0liver : Cryptocurrencies are often celebrated as a triumph of technology over the State, a total and emancipating independence, and yet down the stack - when you hit dirt and wire - the reality is quite different https://www.theguardian.com/ ... @techwontsaveus : “Kazakhstan's crypto mining farms are mostly powered by ageing coal plants which ... are a headache for authorities as they seek to decarbonize the economy. Since the old plants are inefficient and carbon-heavy, they generate an outsize amount of pollution."https://www.theguardian.com/ ... Axel Merk / @axelmerk : Let me get this straight: the Russian military is heading to Kazakhstan to help restore order. Catalyst for the unrest is high energy prices. And crypto mining consumes ~1.2GWt according to energy ministry. So does crypto mining trigger revolutions? https://www.theguardian.com/ ... Peter Ungphakorn / @coppetainpu : Kazakhstan miners hit by unrest Which miners? Chromite? Wolfram? Lead? Zinc? Manganese? Silver? Uranium? No. These miners: “The move would have probably prevented Kazakhstan-based miners from accessing the bitcoin network.” https://twitter.com/...

Fred Walton / @fredwalton216 : Kazakhstan became last year the world's second-largest centre for bitcoin mining after the United States, according to the Cambridge Centre for Alternative Finance, after major hub China clamped down on crypto mining activity. https://twitter.com/...

Context & Ripple Effects
Kazakhstan had already moved to ration winter power for registered miners after relocations from China and illegal mining contributed to blackouts. The internet shutdown adds a separate operating dependency: a major mining centre can lose output even when its machines and power supply remain in place.
The disruption also foreshadows the pressure described in coverage of miners leaving Kazakhstan as power constraints tightened. Kazakhstan’s ageing coal-powered mining base ties the sector’s growth to both grid reliability and the state’s tolerance for its energy demand.
First-order effects
- An estimated 15% of global Bitcoin miners went offline during Kazakhstan’s connectivity outage, immediately reducing mining activity from the world’s second-largest hub.
- Bitcoin fell below $43,000 during the disruption, while Kazakhstan-based mining operators lost the network access required to participate until service returned.
Second-order effects
- Kazakhstan’s registered miners face compounded execution risk: the existing power-rationing regime can constrain operations even after internet service is restored.
- Mining operators that relocated from China must weigh Kazakhstan’s concentration benefits against outages, grid limits and state intervention, reinforcing the incentive to distribute capacity across jurisdictions.
Third-order effects
- Bitcoin mining is becoming less defined by cheap electricity alone; reliable connectivity, grid headroom and political stability are becoming co-equal location requirements.
- As mining loads strain ageing, coal-powered systems, host governments are likely to treat large mining fleets as infrastructure-policy issues rather than ordinary industrial customers.
The trend: Bitcoin mining is shifting from a search for low-cost power toward a broader assessment of jurisdictional infrastructure and policy risk.
