Microsoft apologized for a prolonged global outage that began on November 12 and disrupted Microsoft 365 products, including Outlook and Teams, for governments, hospitals, schools and businesses worldwide. The company said neither AI nor malicious actors were at fault, describing the cause as an underlying infrastructure issue introduced during a network capacity upgrade that surfaced after a recent network change. Microsoft said it had addressed the underlying issue and was restoring service to remaining customers and regions, and that recovery was slower than many would have liked but was brought back gradually to ensure stability. It said it would publish a more detailed incident report once its internal review is complete. PC Gamer noted that speculation had linked the outage to vibe-coding, given Microsoft's push for company-wide AI adoption, and pointed to the company's recent layoffs and buyout offers as context for the reliability questions.
