Microsoft exits UK data center agreement

According to reports published on October 18, 2026, the project has faced repeated delays and significant electricity grid connection problems. Grid officials reportedly warned that sufficient power might not become available until the 2030s. Microsoft did not disclose its reason for terminating the agreement.
