The UK is calling time on its copper networks, and thousands of telephone exchanges across the UK are set to be closed in the coming years.

The end of an era, some of these buildings date back around 100 years or more. If recent history is anything to go by, many will be turned into residential buildings.

Lisa Kinch, a historic places adviser for Historic England and associate lecturer at the Manchester School of Architecture, did her PhD research on telephone exchanges in the UK, giving her a unique view on these buildings and their historical context.

We discuss her research and the unique place the UK's telephone exchanges have in the country's architectural history.

While critical infrastructure has always been the backbone of the digital landscape, the recent data center boom has caused more people than ever before to become aware of the industry and consider the career opportunities it might have to offer.

However, like the tech industry writ large, there’s a perception amongst some outside of the critical infrastructure sector that its workforce lacks diversity and therefore isn't an industry in which they could excel professionally.

In this episode, Lizzy McDowell, director of marketing, Kao Data, tries to dispel some of the myths about the industry and discusses the importance of promoting diversity within the data center sector and why there’s never been a better time to consider a career in critical infrastructure.

DCD speaks to Dr. Tim Gregory, nuclear scientist at Sellafield, the UK's national nuclear laboratory, and author of the best-selling book Going Nuclear, about the history of nuclear power, how it actually works, and whether it can play a key role in powering the growth of AI both in the UK and further afield.

This episode is a bit different.

With the festive period officially peaking, DCD decided to change tack and instead give you a "year in review," where we talk about our favorite stories from 2025.

Join Charlotte Trueman, Zachary Skidmore, Georgia Butler, and Paul Lipscombe as they cover their respective beats.

We hope you enjoy it - and happy holidays!

With data centers in space all the rage, we chat with Sophia Space's Cyrill Glockner about the company's step-by-step approach to putting compute in orbit.

The UK wants more data centers. The government’s AI Opportunities Action Plan, announced in January, is driving operators to look outside of Greater London. We talk to Lee Myall, CEO of Neos Networks – a B2B fiber provider in the UK – about the state of the UK’s connectivity infrastructure, what kind of delays are faced by data center operators in the country, and the impact of AI workloads on fiber buildouts.

At DCD, we frequently cover stories about data centers getting funding, mergers and acquisitions, and investment in general. But we rarely get to talk to the investment bankers about it. 

In this episode, we discuss the current financial market in the data center industry - the trends Pryor is seeing, and the inevitability of the AI bubble. Tune it to hear what an investment banker focused on the technology sector thinks of the current climate. 

DCD speaks to Drew Turner, director of global decarbonization solutions at Danfoss, about how data center waste heat can be best utilized across district heating systems in Europe and further afield.

AtlasEdge emerged in 2021 after Liberty Global and Digital Bridge combined their European assets to make an “Edge” data center player on the continent. Initially, the company targeted smaller data centers - previously positing 4-6MW as the largest it would deploy when talking to DCD, but things have changed. The world has changed. 

Durvasula was hired in May 2024 and has since been leading the company through the new era, one where it's embracing larger facilities that before, and that’s for one simple reason: AI. 

We discuss the changing strategy and what AtlasEdge looks like today.

GridCARE is utilizing AI to identify hidden capacity on the grid, enabling significantly faster connection times for data centers.

We speak to its CEO - Amit Narayan - to find out how.
