Microsoft pauses some data‑centre builds

Microsoft has slowed or paused some data-center projects after months of breakneck building for artificial intelligence, including a $1 billion campus plan in central Ohio. (reuters.com) The clearest confirmed example came on April 8, when Microsoft said it was no longer moving forward with three planned sites in Licking County, Ohio, covering New Albany, Heath and Hebron. The company said it will keep the land, preserve two sites for farming for now, and still fund agreed roadway and utility upgrades. (datacenterdynamics.com) That Ohio pullback followed a March 26 Reuters report that TD Cowen analysts had identified about 2 gigawatts of canceled or deferred projects in the United States and Europe over six months. The analysts said the retreat pointed to supply running ahead of Microsoft’s current demand forecast. (reuters.com) A data center is a warehouse of servers, networking gear and power equipment that runs cloud software and trains or serves artificial-intelligence models. Microsoft had been expanding that footprint aggressively enough in January 2025 to say it expected to spend $80 billion in fiscal 2025 on artificial-intelligence-enabled data centers, with more than half of that in the United States. (blogs.microsoft.com) The shift matters because Microsoft has been one of the companies setting the pace for the artificial-intelligence infrastructure boom since OpenAI’s ChatGPT launch in late 2022. In its fiscal first-quarter 2026 results on October 29, 2025, Microsoft still said customer demand for its cloud and artificial-intelligence services was growing and called its network a “planet-scale cloud and AI factory.” (microsoft.com) Microsoft has not described the moves as a broad retreat. In its statement on the Ohio decision, the company said earlier investments had left it “well positioned” to meet current and rising customer demand, and said it may “strategically pace or adjust” infrastructure in some areas while continuing to grow in all regions. (datacenterdynamics.com) Other projects have also been slowed for reasons Microsoft framed differently. In Mount Pleasant, Wisconsin, the company paused parts of a $3.3 billion buildout in January 2025 while reviewing designs, while saying the first phase was still on track to open in 2026 and that its overall commitment remained intact. (wpr.org) Analysts have tied some of the pullback to changes in Microsoft’s relationship with OpenAI and to uncertainty over how much new computing power customers will absorb in the near term. Reuters reported TD Cowen said Microsoft’s reduced leasing was “largely led” by a decision not to support additional OpenAI training workloads. (reuters.com) The immediate picture is not that Microsoft stopped building, but that it is choosing projects more selectively after a year of record spending. That leaves local officials waiting on paused sites, while investors and rivals watch whether artificial-intelligence demand catches up with the capacity already financed. (microsoft.com)
