A long-form look inside Digital Realty's Ashburn data center, where chief engineer James Waddy walks 30,000 steps a day inspecting cooling, power and fiber systems—acting as a "human sensor" before alarms fire. The piece covers the push from 99.999% to 99.9999% uptime (6 minutes to 30 seconds of yearly downtime), micro-welding of 8-9 micron fiber cores, and an AI-driven hiring crunch: 2,700 US data centers in operation, 400 under construction, job searches up 8x since 2022, with skilled blue-collar pay 42% above peers. It also notes community pushback, including a stalled $500M Atlanta project.
