Services affected by the Microsoft Azure outage include, but are not limited to, App Services, Azure Active Directory B2C , Azure Communication Services , Azure Databricks , Azure Healthcare API, Azure Maps , Azure Portal , Azure SQL Database , Azure Virtual Desktop , Azure Container Registry , Azure Media Services , Microsoft Security Copilot , Microsoft Defender External Attack Surface Management , Microsoft Entra ID , Microsoft Purview , Microsoft Sentinel , and Azure AI Video Indexer .
While error rates and latency have returned to pre-incident levels, some customers may still be experiencing issues and the company is continuing to work to mitigate this long tail.
Microsoft explained the incident, saying, 'An inadvertent change to tenant configuration in AFD caused a widespread service interruption, impacting both Microsoft services and customer applications that rely on AFD for global content delivery. The change resulted in an invalid or inconsistent configuration state, which prevented many AFD nodes from loading properly and increased latency, timeouts, and connection errors in downstream services.' 'As unhealthy nodes dropped from the global pool, traffic distribution among healthy nodes became uneven, magnifying the impact and causing intermittent availability even in partially healthy regions. We immediately blocked all configuration changes to prevent further propagation of the problem and began deploying a 'last known good' configuration across our global fleet. Recovery required reloading configurations across many nodes and gradually redistributing traffic to avoid overloading nodes as they returned to service. This careful and gradual recovery was essential to stabilizing our systems, restoring scale, and preventing a recurrence of the issue.'
Microsoft explained that the cause of this issue was a glitch in the tenant settings deployment process. A software flaw appears to have bypassed the safety validation of a protection mechanism designed to verify and block incorrect deployments, causing the failure. Microsoft subsequently reviewed its safety measures and immediately implemented additional validation and rollback controls to prevent similar issues from occurring in the future.
At the time of this issue, connection issues were confirmed for multiple Microsoft services, including Microsoft 365, Xbox, and Minecraft.
TechCrunch also pointed out that 'websites of companies like Costco and Starbucks are also inaccessible.'
In terms of cloud computing services, Amazon's AWS recently experienced a major outage.
A massive AWS outage caused half of the web to go down, resulting in economic losses of tens of trillions of yen. Some point out that this is evidence that talented engineers are leaving AWS.
