Step inside the buildings that make it, and the magic evaporates. What is left is noise, heat, metal, and an enormous appetite for power.\n\nAxios’s Amy Harder [toured](https://www.axios.com/2026/07/23/inside-data-centers-powering-ai-boom) a test server hall run by Digital Realty in Ashburn, Virginia, the heart of America’s “data center alley.”\n\nThe first thing she noticed was the sound, which she called “demented white noise.” It comes from fans fighting the heat of racks of AI chips. A glass floor showed the cooling pipes running beneath her feet.\n\nAt the bottom of one closet-sized rack sat a gold-coloured Nvidia system. The colour is deliberate, if fake. “Gold is associated with high value and performance,” an Nvidia spokesperson said.\n\nThe value is real enough. “That’s about $1 million right there,” a Digital Realty engineer said of the rack.\n\n## Built to be boring\n\nFor all the money, a data centre is dull by design. “If excitement is happening inside a data center, something has probably gone wrong,” Harder wrote. From outside, the buildings are windowless warehouses.\n\nThe drama is in the [power](https://thenextweb.com/news/ai-data-centres-gas-plants-clean-energy-fight) and the cooling: substations, water towers, or long rows of industrial air conditioners.\n\nThe scale shows in the details.\n\nHarder counted almost 40 diesel generators bolted to one building, for backup only, the company said. Virginia’s grid, which normally feeds the site, runs largely on gas and nuclear. The nearby Digital Dulles campus could eventually hold 13 data centres, a bet worth more than $10bn.\n\nCooling here will lean on energy rather than [water](https://thenextweb.com/news/meta-data-centre-contractor-wyoming-water-contamination-cheyenne), so no giant towers.\n\n## Why the doors stay shut\n\nGetting in is the hard part. Some operators refused a tour outright. Others demanded [non-disclosure agreements](https://insideclimatenews.org/news/13072026/alabama-data-center-non-disclosure-agreement/), and server halls are usually off-limits. That secrecy, Harder argued, is part of what feeds the [backlash](https://thenextweb.com/news/ai-data-centre-backlash-amazon-engineers-ferc) now spreading through communities worried about [power bills and water](https://thenextweb.com/news/redfin-ai-data-centers-nimby-virginia-schools).\n\nShe left convinced firms could show the public far more without giving away secrets.\n\nThe [buildout](https://thenextweb.com/news/australia-28bn-data-centre-project) is only accelerating. Digital Realty is scouting innovation labs in Singapore, São Paulo, and Johannesburg. AI’s physical footprint is growing fast, and mostly out of sight.\n\nThe less people see of it, the more they seem to distrust it, which may be the industry’s real design flaw.\n\n## Get the TNW newsletter\n\nGet the most important tech news in your inbox each week.", "url": "https://wpnews.pro/news/inside-the-data-centres-powering-ai-gold-racks-demented-noise-and-40-diesel", "canonical_source": "https://thenextweb.com/news/inside-ai-data-centre-ashburn-secrecy-backlash", "published_at": "2026-07-23 15:02:15+00:00", "updated_at": "2026-07-23 16:01:27.429656+00:00", "lang": "en", "topics": ["artificial-intelligence", "ai-infrastructure", "ai-ethics"], "entities": ["Digital Realty", "Nvidia", "Amy Harder", "Axios", "Ashburn", "Virginia", "Digital Dulles"], "alternates": {"html": "https://wpnews.pro/news/inside-the-data-centres-powering-ai-gold-racks-demented-noise-and-40-diesel", "markdown": "https://wpnews.pro/news/inside-the-data-centres-powering-ai-gold-racks-demented-noise-and-40-diesel.md", "text": "https://wpnews.pro/news/inside-the-data-centres-powering-ai-gold-racks-demented-noise-and-40-diesel.txt", "jsonld": "https://wpnews.pro/news/inside-the-data-centres-powering-ai-gold-racks-demented-noise-and-40-diesel.jsonld"}}
