Cloud computing has become an important part of digital transformation across public services. However, growing dependence on large technology providers also raises questions about resilience, infrastructure visibility and data sovereignty.
A recent Computer Weekly investigation has mapped the public internet footprint of the UK’s 48 police forces using publicly available DNS records. The analysis found that 47 of the 48 forces had at least one connection to a US hyperscale provider, while 46 routed their email through Microsoft 365.
The findings provide a useful technology insight into how deeply cloud services have become embedded in critical public sector infrastructure.
Microsoft Has Become a Major Part of Police IT
The investigation found that Microsoft has a particularly strong presence across UK policing. Of the 48 forces analysed, 46 route email through Microsoft 365. Only the Ministry of Defence Police and Police Scotland were identified as not doing so.
Microsoft also accounted for 773 routable DNS records in the analysis, compared with 161 for Amazon and two for Google. These figures highlight the concentration of infrastructure around a small number of major technology providers.
Consequently, cloud strategy is becoming an important part of the wider IT industry news landscape, particularly for organisations responsible for highly sensitive information.
What the DNS Analysis Reveals
Computer Weekly analysed public DNS records associated with the 48 police forces. The research collected root records, common policing related subdomains and passive Certificate Transparency records, producing 3,822 individual DNS records.
The records were then mapped to registered owners using RDAP and categorised according to whether they were associated with hyperscalers, cloud and software providers, third party hosting, internet service providers or police owned infrastructure.
Importantly, the investigation notes that the hyperscaler figures represent a lower bound because some records could not be resolved to an owner. Therefore, the results should be understood as an analysis of publicly visible infrastructure rather than a complete inventory of every internal system.
The Challenge of Cloud Sovereignty
One of the most significant issues raised by the analysis is the combination of UK infrastructure with services operated by US controlled technology companies.
Computer Weekly found that 46 of the 48 forces had a mixture of UK sovereign infrastructure and services potentially exposed to the US Cloud Act. The investigation describes this as a tangled hybrid environment.
This does not automatically mean that sensitive information is being accessed improperly. Instead, it highlights a governance challenge. Organisations need to understand where systems are hosted, who controls them, which jurisdictions may apply and how access can be managed during a disruption.
Resilience Becomes a Bigger Technology Priority
Cloud adoption can provide scalability, flexibility and access to sophisticated technology. Nevertheless, concentration around a small number of providers can create questions about resilience.
For critical public services, technology teams need visibility across cloud platforms, network connections, identity services and third party suppliers. Additionally, they need contingency plans for situations where a major provider experiences an outage or where access to an external service is disrupted.
This is where digital transformation needs to move beyond cloud migration. Modernisation should also include resilience planning, infrastructure monitoring and clear recovery strategies.
The Ministry of Defence Police Provides a Different Model
The investigation identified the Ministry of Defence Police as the only force without a connection to Microsoft, Amazon or Google in its public DNS footprint. Its visible infrastructure was associated with Cloudflare and Ministry of Defence owned infrastructure.
This does not establish that one infrastructure model is universally better than another. Instead, it demonstrates that different approaches to infrastructure ownership and cloud dependency exist within UK policing.
The comparison also shows why technology leaders need to evaluate infrastructure according to operational requirements rather than simply following industry adoption patterns.
Third Party Infrastructure Adds Another Layer
Hyperscalers are only one part of the wider technology ecosystem. The investigation also identified significant dependencies involving telecommunications companies, hosting providers and other technology organisations.
BT represented the largest individual third party dependency in the analysis, while Virgin Media and Nominet also appeared across the public DNS footprint. Police owned infrastructure represented a relatively small proportion of the routable records examined.
As a result, understanding technology risk requires more than identifying the primary cloud provider. Organisations also need to understand the wider network of suppliers and services supporting their digital infrastructure.
What This Means for the Wider IT Ecosystem
The findings have implications beyond policing. Many organisations are combining cloud platforms, software as a service, managed infrastructure and third party connectivity as they modernise their operations.
Meanwhile, HR trends and insights can become relevant because cloud transformation requires skilled cybersecurity, infrastructure and data professionals. Finance industry updates also increasingly focus on technology resilience because operational disruption can have significant financial consequences.
Similarly, Sales strategies and research and Marketing trends analysis increasingly depend on reliable cloud platforms. Customer systems, analytics, communication tools and digital campaigns can all rely on external infrastructure.
Insights for the Future of Cloud Infrastructure
The UK police cloud landscape demonstrates how digital transformation can create both opportunities and new dependencies. Cloud platforms can support modernisation, but technology leaders also need clear visibility into infrastructure ownership, supplier relationships, data location and operational resilience.
The Computer Weekly analysis does not establish that hyperscaler adoption itself caused security problems. Instead, it provides evidence of the scale of external infrastructure connections across UK policing and raises important questions about dependency and sovereignty.
For organisations modernising their technology environments, the practical lesson is to treat cloud architecture as an ongoing governance responsibility. Technology insights should therefore focus not only on adopting new platforms but also on understanding how those platforms fit into resilience, security and long term digital strategy.
