Microsoft's widely used cloud services, including Outlook, Teams, SharePoint, and Copilot, suffered a significant global outage for nearly 24 hours, disrupting business communications and productivity for users in over 70 countries. The technology giant confirmed the disruption was due to a technical failure and not a cyberattack or issues with artificial intelligence agents.
Technical Glitch Halts Global Operations
The extensive downtime, which began late Thursday and persisted through Friday morning, was traced back to an issue introduced during an earlier network capacity upgrade. A more recent network change brought this underlying problem to the surface, according to Microsoft's official statement.
Microsoft issued an apology to its customers and partners, emphasizing its commitment to service reliability. "We are deeply sorry for the disruption this incident has caused our customers and partners. We know the trust they place in our services and take that responsibility extremely seriously," the company stated on social media.
Widespread Impact Felt Across Industries
The Microsoft global outage had far-reaching consequences beyond internal employee communication. In India, for instance, customer-facing operations for major airlines like IndiGo and Akasa Air were affected, with both reporting issues with email support. IndiGo advised customers that it might not be able to receive emails, while Akasa Air noted delays in its email services. Air India temporarily rerouted its email infrastructure to maintain customer contact, though its flight operations remained unaffected.
Financial services firms and other businesses also reported difficulties, impacting access to research materials and client interactions, highlighting the critical reliance on Microsoft's cloud ecosystem for daily operations.
Gradual Restoration and Underlying Cause
Engineers worked to restore affected infrastructure, with services returning gradually in stages. Microsoft explained this deliberate, phased approach was taken to validate stability at each recovery stage, ensuring a more stable restoration despite taking longer. At its peak, the outage generated over 130,000 reports of Outlook problems on outage-tracking websites.
The company reiterated that the incident was purely a technical issue, not related to malicious activity. "This was a technical issue not related to cyber or AI / agents," Microsoft confirmed, addressing concerns about the nature of the disruption. A full post-incident report is expected once their comprehensive review is complete.
