Microsoft Attributes Global Service Outage To Network Technical Fault, Rules Out Cyberattack Or AI

ANKARA, Nov 14  – Microsoft has confirmed that the widespread global outage disrupting its cloud and productivity suite was caused by an internal technical fault unrelated to cyberattacks, artificial intelligence, or AI agents, issuing a formal apology to customers and partners as final restoration efforts continue.

According to Anadolu Ajansi, the technology giant stated on Friday, November 13, 2026, that it traced the disruption to an underlying problem introduced during an earlier network capacity upgrade that was inadvertently triggered following a recent network change.

“This was a technical issue not related to cyber or AI / agents,” Microsoft said in an official statement.

While confirming that the root cause had been resolved and core services were demonstrating broad stability, Microsoft noted that staged restoration remained underway for remaining affected users and regions.

“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 added.

Phased Recovery and Affected Microsoft 365 Services

Due to the massive global scale of user demand, Microsoft opted for a gradual, phased recovery process—verifying system stability at every stage—and pledged to publish a comprehensive post-incident review upon completing its internal investigation.

“While this took longer, it helped ensure a stable restoration,” the company explained.

The disruption originated on Thursday with Exchange Online—the backend infrastructure powering business email via Outlook—and persisted into Friday, cascading into dependent Microsoft 365 features such as Microsoft Teams calendars, Copilot, and SharePoint.

The prolonged outage interrupted daily communications across enterprises, educational institutions, and government agencies globally, with lingering access issues and email delays reported among some users as systems stabilized.

Root Cause, Impacted Applications, and Recovery Status

Key technical findings, service disruptions, and corporate commitments include:

• Root Cause: Underlying flaw introduced during an earlier network capacity upgrade and triggered by a recent network change; explicitly unrelated to cyberattacks, AI, or AI agents.
• Outage Timeline: Began Thursday, Nov 12, 2026, and extended into Friday, Nov 13, 2026.
• Affected Services: Exchange Online (Outlook business email) and dependent Microsoft 365 features including Teams calendars, Copilot, and SharePoint.
• Recovery Approach: Phased restoration to safeguard stability under heavy demand, accompanied by a formal apology and a commitment to release a full post-incident report.
