LONDON, UK, 5th May 2026
Neos Networks, the leading business connectivity provider, is working with Cornerstone, the UK’s leading mobile infrastructure services provider, to provide connectivity services to UK “microscaler” StonesThro, delivering connectivity to support distributed sovereign edge cloud infrastructure.
Unlike hyperscalers that centralise infrastructure in major data centres, StonesThro operates as a microscaler, distributing cloud and AI compute power to localised sites across the UK. By connecting these regional hubs into Neos’ national, business‑dedicated network, StonesThro and Cornerstone can serve end users in key urban and industrial areas. This distributed model is already unlocking new capabilities for sectors where proximity is important for functionality, ranging from autonomous vehicles and large enterprises to local authorities and high-security sovereign software providers. The planned deployments will utilise Cornerstone’s national infrastructure footprint, enabling distributed cloud nodes to be deployed at scale.
For Critical National Infrastructure (CNI) customers handling sensitive data, the UK-sovereign model offers an alternative to international cloud providers. Last year, in partnership with Network Rail, Neos Networks announced Project Reach, the biggest core fibre network deployment in decades. Neos’ UK-wide network will support Cornerstone and StonesThro in delivering secure connectivity to CNI operators, such as those in the rail industry, who often require domestic infrastructure.
“Our national footprint is the ideal backbone for Cornerstone and StonesThro’s edge AI cloud,” comments Lee Myall, CEO at Neos Networks. “Through our high-capacity connectivity, we are providing the UK-wide sovereign coverage, optionality and technical resilience required for high-security projects. We are proud to power the infrastructure that will enable the next generation of real-time applications and critical national services.”
“Working with Neos Networks and Cornerstone allows us to develop and scale sovereign edge AI infrastructure with national reach,” says Andy Bates, CISO at StonesThro. “Their position as the UK’s largest B2B connectivity provider, alongside their access to the rail network through Project Reach, makes them the ideal collaborator to help us deliver a local solution for local people.”
Together, Neos Networks, Cornerstone and StonesThro are supporting the UK government’s AI and data centre ambitions through an alternative infrastructure model. Rather than concentrating compute power in large southern data centres, StonesThro's distributed approach moves AI capabilities closer to where they’re needed and closer to where power is generated, addressing both the UK’s data centre capacity shortage and grid transmission challenges.
