Introduction:
In today’s AI-driven infrastructure landscape, connectivity is becoming just as critical as compute itself. In many cases, data centre (DC) operators must address network and interconnection requirements long before GPU capacity or compute resources are even deployed.
Connecting to the emerging neocloud ecosystem is rarely straightforward. These providers operate across multiple, geographically diverse data centres, creating significant complexity around low-latency connectivity, scalability, and resilient inter-site networking.
That’s where Zayo Europe can help. As a dedicated DC-to-DC connectivity provider, we simplify access between data centres and cloud environments, enabling operators to connect seamlessly to the distributed AI infrastructure ecosystem.
At the same time, ongoing debates around whether AI represents a market bubble continue to fade. AI is not simply another technology trend; it represents a fundamental shift in how industries operate and innovate. History has seen similar scepticism during the emergence of transformational technologies such as the printing press, the telephone, and the automobile. Each reshaped society and the global economy in ways that were initially underestimated. AI is following the same trajectory: not a temporary cycle, but the foundation of a new technological paradigm.
Feedback from the DataCloud event in Cannes, 2026:
The overwhelming feedback from talking with industry leaders at the DataCloud 2026 event in Cannes was that the people building and planning new data centre campuses across the UK and Europe need connectivity solution design advice. Complex infrastructure challenges require more than products, they require the kind of engineering-led solutions that Zayo Europe build by working directly with all partners to design and deliver environments aligned to operational, regulatory, and commercial requirements, not just for now, but also for the future. Architecting low-latency, high-resilience connectivity so data centres can place demanding compute and AI workloads close to distributed user bases isn’t just want we do, it’s what we excel at. Specialist engineers, exceptional service standards and performance, and an extensive, fully owned, future-ready network assures project delivery, confidence and control.
What is the UK AI Growth Zone programme?
The UK Governments AI Growth Zones (AIGZ) programme is ambitious, and central to the UK’s economic and national security strategy. The programme looks to unlock up to £100bn in private investment and create over 10,000 jobs nationally. Over £70bn in AI infrastructure investment was secured in just 12 months, making this a successful, and transformational programme that’s being delivered at pace.
The programme will accelerate the UK’s ability to scale AI ready data centre infrastructure by removing planning and grid bottlenecks and creating regions where data centre investment can happen rapidly.
Why do we need AI Growth Zones?
The need for UK AI Growth Zones is driven by an urgent demand for domestic data centre capacity, and the scaling of sovereign AI required for economic growth and public services. According to the Tony Blair Institute for Global Change (Tech & Digitalisation Paper, July 2025), The UK requires three times its current data centre capacity to meet projected needs, creating a race to build reliable, high-density server environments.
These zones directly influence, and are influenced by, the strategies of both hyperscalers (AWS, Google, Microsoft, Meta, etc.), and the fast-emerging category of neocloud providers (CoreWeave, Lambda, Nebius, Crusoe, etc.), and those who build for them such as the data centre provider nScale.
Neoclouds increasingly shape the UK’s AI infrastructure ecosystem, driving high-density rack footprints, requiring a refresh of power and cooling infrastructure, hence they are securing massive UK investment. This positions them as central eco-system players in regions designated as AIGZs.
As well as creating the physical foundation for the UK to realise the potential of AI, the agenda stretches to siting capacity further away from traditional hub locations, releasing pressure on the grid and bringing new economic growth and skilled jobs to other parts of the United Kingdom.
Essential ingredients for AI Growth Zones:
- Land
- Power
- Compute partners
- Connectivity
- Reduced planning and grid bureaucracy
Compute partners are essential to AIGZ’s, they are a private-sector technology or data centre developer that builds and operates large-scale computing infrastructure within the regional hubs. AI compute requires high-performance hardware to train models and run inference at scale. A compute partner commits to building large-scale data centres, ranging from 100MW to 500MW or more. As these data centres are so power-hungry, compute partners collaborate with local energy providers to build sustainable, ‘behind-the-meter’ power grids. Through this public-private collaboration compute partners receive fast-tracked planning permission grid connection priority, and potential energy cost discounts. In return they provide guaranteed, secure computing capacity to support local research, startups, and national public-sector priorities.
Available land, with renewable power and reduced bureaucracy were the initially key drivers for the project, however connectivity is as important. It’s also a strategic priority, despite the additional complexity added in connecting remote sites in rural areas with hyperscale-ready network topologies.
AI Growth Zones are intended to host GPU dense training centres, which require enormous east west data movement between sites. Without backbone fibre connectivity, compute clusters cannot scale or interconnect at AI training speeds.
Where are UK AI Growth Zones located?
Initial AIGZs are located in Oxfordshire, North and South Wales, the North-East, and Scotland. Zayo Europe’s reach means it is the prime connectivity provider for any AIGZ data centre, bringing Tier-1, high-capacity, low-latency, and resilient fibre connectivity infrastructure with the scale to connect directly to multiple ISPs, telecommunications carriers, and cloud providers and enabling the phenomenal projected data volumes AI will undoubtedly generate.
Zayo Europe is proud to be the partner of choice for the majority of AI Growth Zone data centres in the UK, and we’re helping to replicate the model in France and other European countries where we provide backbone fibre infrastructure connectivity.
Critical National Infrastructure Classification:
Since 2024, UK data centres have been classified as Critical National Infrastructure (CNI), significantly raising their priority in planning, funding, and regulatory treatment. The UK Government emphasise that onshore data centre capacity is essential for sovereign AI capability, data security, and resilience.
Network resiliency is now a necessity rather than a luxury, and the government is right to classify data centres as critical national infrastructure, however, it’s equally important to recognise the role that the rest of our network infrastructure plays. The data centre can be located within a national border, but the data is sovereign only when we can account for where it flows, and when it leaves the country. Data transport is core to the operation of a data centre and if it fails so does our CNI, meaning the supporting network infrastructure is as critical as the data centre building itself.
Data centre locations rely on network infrastructure, both terrestrial and subsea, to connect to each other and to the internet. Navigating disruptions, such as those experienced during the Olympics or cyber incidents like Crowdstrike, relies heavily on the security of this underlying infrastructure. It’s important that the government, infrastructure providers and data centre operators work together so that all elements of this critical national infrastructure function reliably. This will enable critical organisations to continue to operate smoothly.
The connectivity operators with the reach, experience, scale and breadth of services to address the pre-requisite needs of hyperscalers, neoclouds and heavily regulated enterprises are few.
