Microsoft exits UK data center deal with Nscale amid power supply delays, clouding IPO prospects

Microsoft has pulled out of a data center deal with British neocloud startup Nscale at a site in Loughton, Essex, according to a report by the Telegraph, dealing a significant blow to the company at a moment when it was pursuing an initial public offering. The Telegraph did not disclose a specific reason for Microsoft's exit, but reported that the site has been beset by a series of delays, with authorities telling Nscale they do not expect a power supply to be connected to the facility until the 2030s.

The loss of the Microsoft agreement comes at a particularly sensitive time for Nscale, which has been working toward an IPO and has been building out a broader partnership with the tech giant elsewhere. Nscale's SEC filings show that the company has separate arrangements with Microsoft covering deployments of tens of thousands of NVIDIA GPUs at European sites including a 200 MW campus in Portugal, but the collapse of the UK deal raises doubts about the startup's ability to fulfill its stated backlog of commitments. Grid access constraints in the UK are a wider infrastructure challenge for the data center industry, and the Loughton setback underscores the risk those constraints pose to neocloud operators seeking to scale quickly ahead of a public listing.
