Microsoft hits a capacity wall

Microsoft is pouring money into artificial intelligence data centres faster than it can bring new capacity online. (livemint.com) On April 23, Microsoft said it would spend A$25 billion in Australia by the end of 2029 on AI infrastructure, cybersecurity and skills, calling it the company’s biggest investment in the country. The company said the plan would expand in-country cloud and AI capacity and train three million Australians by 2028. (microsoft.com) Satya Nadella announced the package in Sydney alongside Prime Minister Anthony Albanese, and Microsoft tied the project to Australia’s data-centre policy settings and national security work with the Australian Signals Directorate and Home Affairs. Microsoft did not publicly name the new sites, power sources or job totals in its announcement. (microsoft.com) (msn.com) A data centre is the warehouse behind cloud software: rows of servers, networking gear and cooling systems that let companies run AI models and rent computing power to customers. The bottleneck is no longer only chips; it is land, electricity, transmission lines, permits and construction schedules. (blogs.microsoft.com) (ft.com) That squeeze is showing up inside Microsoft’s own business. Mint reported on April 23 that Microsoft has struggled to expand capacity quickly enough to support both its own AI products, including Copilot, and outside cloud customers. (livemint.com) Microsoft has been trying to close the gap by leasing more facilities. Bloomberg reported in March that Microsoft added about $50 billion in lease commitments in its most recent quarter, and reported again on April 14 that the company agreed to rent extra capacity in Narvik, Norway, including 30,000 Nvidia Vera Rubin chips from nScale. (bloomberg.com 1) (bloomberg.com 2) The company’s spending surge has been building for more than a year. Microsoft said in January 2025 that it was on track to invest about $80 billion in AI-enabled data centres during fiscal 2025, and its 2025 annual report said Azure revenue topped $75 billion for the first time. (blogs.microsoft.com) (microsoft.com) Australia fits that expansion map because Microsoft already has local data-centre operations there and has been increasing its commitments. In 2023, the company announced a A$5 billion Australian investment; the new A$25 billion pledge is five times larger. (microsoft.com 1) (microsoft.com 2) Microsoft says the build-out will help meet demand for cloud and AI services, while critics and local observers are still asking where the facilities will go and how they will be powered. Until those answers are clearer, the company’s AI push is still running into the oldest limits in infrastructure: concrete, cables and megawatts. (microsoft.com) (msn.com)
