Microsoft Azure Outage: What Happened and How It Was Fixed

Microsoft’s Azure cloud computing platform suffered a major outage on Wednesday. The incident happened between 15:45 UTC on 29 October and 00:05 UTC on 30 October. It affected Microsoft services using Azure Front Door (AFD), including App Service, Media Services, Microsoft Purview, and more.

Moreover, many websites went down, since Azure is one of the big three global cloud infrastructure providers. Users also reported problems with Microsoft 365, Minecraft, Xbox, and related websites on Downdetector.

According to Azure’s preliminary post-incident review, it was caused by an “inadvertent tenant configuration change.” It led to many AFD nodes failing to load properly, which then resulted in latencies, connection errors, and timeouts. Basically, a malfunctioning tenant configuration triggered a chain reaction failure.

To combat this, Azure temporarily blocked all customer configuration changes and deployed the last known stable build.

During the incident, the official Microsoft 365 Status and Azure Support accounts were providing updates on X. For a time, even the Microsoft Service Health Status page was down. Around 18:30 UTC on 29 October, a fixed configuration was globally pushed and gradually implemented.

The Microsoft 365 Status X account stated: “We’re deploying a previous healthy configuration to the affected infrastructure to resolve this issue. This is being done in tandem with efforts to rebalance traffic across healthy infrastructure to mitigate impact quickly.”

Finally, Microsoft confirmed that the AFD impact for customers had been mitigated at 00:05 UTC on 30 October 2025. Users can expect more details when the final Post Incident Review comes out, expected within 14 days. Azure Service Health alerts can also notify them with emails, SMS, and webhooks.

Unfortunately, this isn’t the first recent failure of its kind. Just nine days ago, a massive Amazon Web Services (AWS) outage suspended many websites and services. According to the AWS service health page, DNS resolution issues were to blame.

This shows that even something as pervasive and global as the internet can be frail. AWS, Microsoft Azure, and Google Services are the three cloud computing giants that hold up most of the infrastructure. If even one of them goes down, the impact is immense.

Amazon is in the lead, with a 30% cloud market share in the second quarter of 2025. Azure is in second place, taking up about 20% of the global cloud market. Meanwhile, Google Services holds 13%. With the recent outages, thousands of users and systems could feel the consequences of this market development.
