As demand for secure, high-performance computing grows, operators are looking below ground for answers. Former mines, military bunkers, and mountain caverns are being reimagined as ultra-secure, energy-efficient data centers.

This supplement explores the rise of subterranean infrastructure, where natural cooling, renewable power, and inherent physical protection combine to deliver sustainability and resilience in equal measure.

Featuring insight from Lefdal Mine Datacenter, CyberFort, and other pioneers, it uncovers how underground facilities are reshaping the future of digital infrastructure, offering unmatched security, stable climates, and a pathway to lower-carbon operations.

Discover how operators are using subterranean design to:

• Cut cooling and energy costs through natural efficiencies
• Enhance security and compliance for sovereign and hyperscale workloads
• Reuse existing underground assets to scale sustainably
