Plus, we learn about prospective national leader Andy Burnham's data center visits, and what the data center indu...

Data center site selection is a crucial step in the construction process, and picking the right piece of land can be the difference between a project succeeding and failing. For AI data center developers with money burning a hole in their corporate back pockets, separating the promising propositions from duds is a time-consuming business. Build thinks it can help with an AI-powered system that it...

Did you know that DCD has a sister publication? In April 2025, DCD acquired networking publication SDx, and with it now having been part of the InfraX family for a year, we thought it was about time we sat down with senior editor Ben Wodecki to give the publication a proper introduction. Tune into the episode to meet Ben and hear about what SDx covers, as well as a bit of a discussion on the key u...

It can seem like GPUs get all the headlines when it comes to AI workloads, but there are a lot more challenges when it comes to handling massive training jobs.  We talk to Pradeep Vincent, Oracle’s Executive Vice President & Chief Technical Architect of OCI, about the importance of power and the oft-overlooked networking in large-scale AI clusters, particularly as we approach multibuilding sca...

DCD catches up with Patrick Halley, president and CEO, Wireless Infrastructure Association, to discuss the requirements of the telecommunications industry’s infrastructure build-out. Halley outlines how AI, fiber, and spectrum are essential for meeting the demands to support these networks, as he examines the opportunities for the mobile carriers, fiber providers, and tower companies. 

With the AI industry fueling a shift away from training and towards inference, and claiming agentic AI as its next frontier, the need for hardware to support workloads that require high-compute and low-latency performance has never been greater. On this episode of Zero Downtime, DCD talks to Sumti Jairath, chief architect at SambaNova, about some of these driving forces, how the semiconductor indu...

DCD speaks to Nayel Brihi, corporate energy analyst at BloombergNEF, about the state of energy procurement over the past year.

It is the 100th episode of Zero Downtime! Before we get into the episode, a huge thank you to all of our listeners - new and those who have been with us since the beginning. In this episode, we are joined by Kevin O'Leary, AKA Mr Wonderful, best known for being on Dragons' Den/Shark Tank, with a recent debut in the Marty Supreme movie.

DCD sits down with the CEO of Sage Geosystems, Cindy Taff, to talk all things enhanced geothermal, and how the technology could power the data centers of tomorrow.

That data centers need insurance goes without saying. Any commercial building will typically be insured against standard damages and risks, but data centers are far more complicated than an average warehouse or office.  One area that has emerged of late is the idea of “SLA” insurance, or Service Level Agreement insurance. Parametrix is one of the pioneering companies in this realm, and we discuss...

Mobile devices require networks to make them function, and these networks are often deployed in places most people wouldn’t dare to visit, such as telecom towers. Some can be found thousands of miles high, but for tower contractors, it’s their everyday job, and across all sorts of weather conditions. Tommy Schuch, a former tower contractor and now documentary maker and founder of Climber Protectio...

With the deployment of 4G and 5G services still an important focus for US carriers, the need for telecoms infrastructure to house this equipment couldn’t be greater, which presents an opportunity for infrastructure companies such as Palistar Capital-backed Symphony Towers Infrastructure. DCD caught up with David Bacino, CEO, Symphony Towers Infrastructure, to discuss his first few months in the ro...

Anyone who has entered a data center will be familiar with the upright rack design that has become standard in data halls around the world. But while piling up the “pizza boxes” has served the industry well for decades, the advent of liquid cooling systems, developed to meet the thermal needs of advanced chips, means a new approach may be needed. Cooling firm Air2O is thinking outside the (pizza)...

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 Manc...
