Microsoft fully restores services after 19-hour global outage

Microsoft has fully restored its services after a major outage lasting approximately 19 hours that left millions of users worldwide without access to Outlook, Word, Excel, Teams, and Copilot. The company confirmed the complete restoration on Saturday morning but has not yet commented on the incident's cost. The outage affected 74 countries and was traced to two technical events: a latent problem introduced during a previous network capacity expansion, and a subsequent configuration change that triggered the issue, saturating the connection management system and disabling servers. Microsoft has ruled out a cyberattack as the cause. The company will release a preliminary report on Monday and a final report by Friday detailing the causes and contingency measures. Microsoft CEO Satya Nadella has remained silent on the incident, and the company's official blog has not addressed the outage. Microsoft 365 has over 450 million subscribers.
