UK Infrastructure Sovereignty: The Hyperscaler Dependency Gap
The Strategic Vulnerability
The United Kingdom’s artificial intelligence ambitions rest upon a foundation it does not control. Despite ministerial commitments to “technological sovereignty” and “strategic autonomy,” UK AI development operates almost entirely within infrastructure owned and operated by three American corporations: Amazon Web Services, Microsoft Azure, and Google Cloud Platform.
This dependency creates a fundamental contradiction in UK AI governance strategy. Government pronouncements emphasise British leadership in responsible AI development whilst the physical and digital infrastructure enabling that development remains under foreign corporate control, subject to extraterritorial jurisdiction, and vulnerable to unilateral policy changes beyond UK governmental influence.
The gap between sovereignty rhetoric and infrastructure reality has profound implications for the UK’s positioning as a “bridge jurisdiction” between regulatory frameworks, its ability to enforce AI governance commitments, and ultimately its capacity to maintain strategic autonomy in a technology sector increasingly recognised as critical national infrastructure.
Procurement Patterns Reveal Systematic Dependency
UK government procurement data demonstrates overwhelming reliance on US hyperscalers across departments responsible for AI policy implementation. The Department for Science, Innovation and Technology, the Cabinet Office AI Unit, and research councils supporting AI development all operate primarily within AWS, Azure, or Google Cloud environments.
Analysis of Crown Commercial Service frameworks shows that whilst UK cloud providers exist as options, actual departmental purchasing decisions consistently favour the three American hyperscalers. This pattern holds across central government departments, arm’s length bodies, and publicly funded research institutions developing AI capabilities the government identifies as strategically significant.
The procurement justifications typically cite technical capability, cost efficiency, and existing integration requirements. These are legitimate operational considerations. However, they systematically subordinate strategic autonomy concerns to immediate procurement convenience, creating compounding dependency with each successive contract renewal.
The Extraterritorial Jurisdiction Problem
UK organisations processing data through US-owned cloud infrastructure remain subject to American legal jurisdiction regardless of data localisation efforts. The US CLOUD Act grants American law enforcement agencies authority to compel US-based cloud providers to produce data stored anywhere globally, creating potential conflicts with UK data protection requirements and strategic interests.
This legal architecture means that UK AI development, including systems the government considers nationally significant, operates within infrastructure where American legal authorities possess compulsory access rights that UK oversight mechanisms cannot prevent or even necessarily detect. The recent Schrems II European Court of Justice decision highlighted these sovereignty tensions, yet UK procurement patterns show minimal adjustment in response.
Government assurances about data residency requirements miss the fundamental issue. Even with data physically stored in UK-based data centres, the corporate entities controlling the infrastructure remain US persons under American law, maintaining the extraterritorial jurisdiction pathway regardless of geographical data location.
Infrastructure Control and AI Governance Credibility
The UK positions itself as a leader in AI safety and governance, hosting the AI Safety Institute and claiming authority to develop international AI governance frameworks. This positioning becomes strategically problematic when the infrastructure underlying UK AI development remains under foreign corporate control subject to extraterritorial jurisdiction.
Consider the practical implications: the UK government commits to enforcing AI governance requirements on systems developed by British organisations, yet those organisations operate within infrastructure where another jurisdiction possesses superior compulsory access rights. This creates an inherent governance asymmetry where UK regulatory authority operates downstream of American legal jurisdiction.
The credibility gap extends beyond technical sovereignty to strategic autonomy questions. When ministerial statements about British AI leadership depend upon infrastructure controlled by corporations subject to US government influence, the distinction between British policy priorities and American commercial or strategic interests becomes operationally unclear.
The “Bridge Jurisdiction” Contradiction
UK government strategy positions Britain as a “bridge jurisdiction” connecting different AI governance frameworks, particularly between the European Union AI Act and emerging international coordination mechanisms. This positioning assumes the UK maintains sufficient independence from both American and European influence to operate as a genuine intermediary rather than a proxy for either pole.
The infrastructure dependency pattern undermines this positioning. A bridge jurisdiction requires the capacity to implement governance requirements independently, ensuring compliance with multiple frameworks without systematic bias toward any single regulatory pole. However, when UK AI development operates predominantly within American corporate infrastructure, the practical ability to enforce requirements that conflict with US commercial or strategic interests becomes questionable.
European observers noting this dependency increasingly view UK bridge jurisdiction positioning as aspirational rather than operational. The practical question becomes whether UK governance commitments carry genuine enforcement authority or whether they ultimately defer to constraints imposed by infrastructure sovereignty gaps.
Policy Recommendations for Infrastructure Rebalancing
Strategic infrastructure sovereignty does not require eliminating US hyperscaler presence in the UK market. It requires establishing genuine alternatives that maintain UK governmental capacity to enforce AI governance commitments independently of foreign corporate infrastructure dependencies.
Immediate Actions:
- Mandate infrastructure sovereignty assessments for all government AI procurement, requiring explicit strategic autonomy justification for hyperscaler dependencies
- Establish minimum thresholds for UK-controlled infrastructure capacity in AI systems the government designates as strategically significant
- Require transparency reporting on extraterritorial jurisdiction exposures in government-funded AI development projects
Medium-Term Development:
- Invest in UK-based cloud infrastructure capacity specifically designed for AI workloads, prioritising governance features rather than competing on cost with established hyperscalers
- Develop procurement frameworks that properly price strategic autonomy, treating infrastructure sovereignty as a legitimate requirement rather than a procurement inefficiency
- Create certification schemes for “sovereignty-assured” AI infrastructure that meets both technical capability and jurisdictional control requirements
Long-Term Strategic Positioning:
- Position UK infrastructure capacity as a European strategic asset, enabling genuine bridge jurisdiction positioning through demonstrated capability to operate independently of both American and EU infrastructure
- Build strategic partnerships with allied nations facing similar sovereignty challenges, creating distributed infrastructure networks that maintain democratic governance whilst achieving operational scale
- Establish the UK as the jurisdictional home for international AI governance mechanisms requiring infrastructure demonstrably independent of any single great power’s compulsory access rights
Conclusion: Sovereignty Requires Infrastructure
The United Kingdom cannot credibly claim AI governance leadership whilst operating almost entirely within infrastructure subject to foreign corporate control and extraterritorial jurisdiction. Bridge jurisdiction positioning requires demonstrated capacity for independent action, not merely aspirational policy commitments.
Current procurement patterns systematically prioritise operational convenience over strategic autonomy, creating compounding dependencies that constrain UK policy freedom with each successive contract renewal. Reversing this pattern requires treating infrastructure sovereignty as a legitimate governance requirement rather than an inefficient procurement barrier.
The gap between sovereignty rhetoric and infrastructure reality ultimately determines whether UK AI governance commitments carry genuine enforcement authority or whether they represent aspirational positioning constrained by dependency relationships the government has chosen not to address. This is not a technical question. It is a strategic choice about whether the UK prioritises immediate operational efficiency or long-term governance autonomy.
