Ask someone to draw the London skyline and, among images of St. Paul’s Cathedral, the London Eye, and the Cheesegrater, a telco tower stands supreme.

For the latest issue of DCD Magazine, we became one of the last journalists to visit the iconic BT Tower, to understand how BT and Openreach are preparing to move out of it and thousands of exchanges as they shift from copper to fiber. Plus, we profile the entire history of the company’s copper usage.

Elsewhere, as AI data center demands increase, so does the industry’s willingness to look beyond traditional power sources. Hyperscalers like Meta and Google are partnering with innovative new geothermal companies to unlock energy from the ground.

Also in this issue, we spoke to two relatively new companies looking to make their mark. Portus hopes to find space at the regional Edge, and has its eye on small-scale data centers in Europe, targeting the kinds of customers that have been forgotten in the AI boom.

CleanArc Data Centers has its eye on larger customers. Its CEO, Jim Trout, talks us through the company’s plans to build hyperscale-focused data centers matched to renewable energy.

Plus, how to build a supercomputer, telco tower terrorists, the film industry’s move to the cloud, and data center security in the AI girlfriend era.
