UK Data Sovereignty protects against losing access to data and services provided by US tech firms. Anthropic’s recent shutdown highlights how real and present this risk truly is.
tl;dr:
What happened? In June 2026, a US government export control directive led Anthropic to abruptly block non-US access to its latest AI models, highlighting the vulnerability of foreign businesses relying entirely on US-based SaaS and cloud providers.
What is the risk for UK businesses? Relying on US Big Tech (including Microsoft 365, Google Workspace, and US AI companies) exposes UK companies to sudden service disruptions, sudden price hikes due to tariffs, and political pressures from US foreign policy.
What is the solution? Transitioning critical infrastructure – such as cloud storage and collaboration tools – to localised UK technology providers that operate strictly under UK legal protections and guarantee true UK data sovereignty.
On 12th June 2026, Anthropic, the American AI company most famous for its Claude products, abruptly blocked access to their latest models for all global customers without notice or warning. The reason? An “export control directive” from the US government, effectively and immediately banning the use of the Fable and Mythos AI models by any non-US citizen.
While limiting access to Software as a Service (SaaS) products by geography isn’t novel in and of itself, the sheer speed and transparency of this government intervention made headlines across the world. Everyone globally, including enterprise businesses, startups, academics, researchers, and individuals, immediately lost access to a product they had paid for, due only to the fact that the US government had deemed it a possible national security risk.
Access was ultimately restored a few weeks later, and the merits of the security risk remain in question (the claims were immediately refuted by Anthropic). More certain, though, is the clear and present power that US government policy has over our access to online services, and how willing and able they are to wield it. Even in the UK and EU, where contractual agreements between users and Anthropic are made with their European subsidiary, access to the models was still revoked at the behest of their US headquarters.
Anthropic aren’t the only major US tech firm to be recently involved in or accused of international service denial. In 2025, Microsoft were accused of limiting access to the email of the International Criminal Court, whose chief prosecutor was subject to American sanctions being imposed by the Trump administration. While Microsoft denied the claims, the Anthropic situation has only confirmed that US foreign policy can and will be used to limit access to the services we rely on. In recent years big US tech firms have sought to “reassure” foreign users with their own “sovereign cloud” offerings, but the protections these offer are not only subject to a change of heart and political pressure, but do very little to protect the smaller businesses, organisations, and individuals in the UK who would be affected by price increases and limited competition due to tariffs, trade agreements, and other political instruments out of our control.
The short version of this is pretty simple; if Trump or any other future US administration wants to pull access to, or increase the prices of your Microsoft 365 or Google Workspace subscriptions, they can, and will.
The answer, as governments and businesses across Europe are starting to demonstrate, is to make a conscious choice about where we source our technology services as UK businesses and citizens. While the UK doesn’t exactly have a perfect recent record on technology policy, the legal protections and political accessibility that come from “buying British” are still (in our opinion) the most effective way of mitigating the risk that US Big Tech introduces.
If your business or personal endeavours are in any way sensitive to access to online services, price changes, or short-notice contractual changes, we highly recommend engaging a UK firm as a technology provider. And if you are looking to secure your business with fully UK-based cloud storage, collaboration tools, and office software, drop us a message about Bigby.drive – putting UK data sovereignty at the heart of your business.
FAQs
UK data sovereignty is the principle that digital data is subject to the laws and governance of the United Kingdom, where it is physically located and processed. An extension of this principle also recommends sourcing online services from UK-headquartered businesses, where the company itself is similarly governed primarily by UK law. For UK businesses, true data sovereignty ensures that data and service access cannot be revoked, modified, or searched by foreign governments (such as via the US CLOUD Act or sudden export control directives), protecting business continuity and compliance.
Yes. Because major tech platforms are headquartered in the United States, they are ultimately bound by US federal laws, executive orders, and foreign policy directives. If a US administration implements strict export controls, trade sanctions, or tariffs, US tech firms are legally obligated to comply, which can result in sudden access restrictions or severe price increases for international clients, including those in the UK.
While many US tech giants offer European or sovereign cloud options, these frameworks still carry risk. They remain vulnerable to parent-company policy changes, US government legal overreach, and macro-political pressures like trade agreements or tariffs. For complete risk mitigation, a native UK cloud service provider is the most reliable alternative.
UK businesses can protect themselves by auditing their software stack and shifting business-critical functions – like cloud storage, email, and collaboration software – to local UK-owned providers. Choosing a British technology provider ensures that your contractual rights, data protections, and service accessibility remain entirely under UK jurisdiction.
