Inside the Data Centers Powering the AI Boom: Why Secrecy Is Fueling Public Backlash

Behind the Invisible AI Boom Lies a Resource-Intensive Physical Endeavor

AI feels invisible to most users—a voice from a phone, an instant answer appearing from nowhere. But step inside the data centers powering the AI boom, and the magic evaporates into something far more tangible: relentless noise, industrial heat, metal racks, and an enormous appetite for power1

1

. Axios reporter Amy Harder recently gained rare access to an innovation lab run by Digital Realty in Ashburn, Northern Virginia, located in what's known as "data center alley"—the world's largest concentration of such facilities2

2

. What she discovered was a resource-intensive physical endeavor operating mostly out of public view, and that secrecy is becoming a problem.

The Physical Reality of AI's Physical Footprint

The first sensation upon entering the test server hall was sound—what Harder described as "demented white noise" generated by fans working to cool racks of AI chips that produce enormous amounts of heat1

. A glass floor revealed cooling pipes running beneath, part of elaborate cooling systems designed to prevent AI hardware from overheating2

2

. At the bottom of one closet-sized rack sat a gold-colored Nvidia system. The color choice is deliberate, though not real gold. "Gold is associated with high value and performance," an Nvidia spokesperson explained1

. The value, however, is genuine—Digital Realty engineer Tor Nyström noted that single rack represents approximately $1 million in equipment2

Power Consumption and Infrastructure at Unprecedented Scale

The scale of power consumption becomes visible in the details. Harder counted almost 40 diesel generators bolted to one building—used only for backup power and occasional testing, according to Digital Realty spokesperson Kevin Gundersen2

. Normally, the campus draws electricity from Virginia's grid, which runs largely on natural gas and nuclear power1

1

. The nearby Digital Dulles campus could eventually hold 13 data centers, representing an investment exceeding $10 billion over the next decade1

. From the outside, these facilities appear as massive, windowless warehouses, with the most visible elements being electricity substations and cooling infrastructure—either huge water-filled cooling towers or rows of industrial air conditioners.

Industry Secrecy Drives Growing Public Backlash

Getting inside these facilities proves extremely difficult. Some operators flatly refused tour requests, while others demanded non-disclosure agreements, with server halls typically remaining off-limits altogether2

2

. This secrecy, Harder argued, is fueling the public backlash now spreading through communities worried about electricity bills, water supplies, and environmental impact1

1

. After touring both the innovation lab and a nearby campus under construction, Harder came away convinced companies can show the public how these facilities work without revealing proprietary information2

2

. The less people see of AI workloads and their infrastructure requirements, the more they seem to distrust them—which may be the industry's real design flaw1

Global Expansion and What to Watch

The buildout is accelerating globally. Digital Realty is scouting locations for additional innovation labs in Singapore, São Paulo, Brazil, and Johannesburg, South Africa2

2

. The company's innovation lab in Northern Virginia opened in September, with a similar facility launching in London in June2

2

. As one of the world's oldest and most established data center operators, Digital Realty's expansion signals the trajectory of AI's global physical footprint2

2

. For communities hosting these facilities, the key questions revolve around power grid capacity, water usage for cooling systems, and whether operators will increase transparency about their operations and environmental impact.
