Microsoft has announced that services are fully restored following a massive global outage that crippled online communications for businesses and governments for over 24 hours. The disruption affected Microsoft 365 offerings, including Outlook, Teams, and the AI assistant Copilot, impacting users across 74 countries and territories.
The IT failure disrupted a wide range of sectors, including healthcare services, hospitals, police departments, airlines, banks, and government operations in countries such as Japan, Singapore, and Australia. While the outage paralyzed government offices and traders globally, the US homeland security chief confirmed there was no Microsoft link to the US air stoppage.
Microsoft attributed the incident to technical issues, specifically server failures, elevated infrastructure loads, and network capacity upgrade issues. The company ruled out any malicious activity, cyber-security incidents, or AI-related causes. Although early efforts to fix the issue were described as having marginal success or not going as expected, a broader rollout of software fixes eventually stabilized the system.
By Saturday morning, the company confirmed that service had been restored to all remaining impacted customers and regions, including the processing of a backlog of emails. Experts stated that the event serves as a stark reminder of the world's heavy reliance on a small group of big tech providers.
