Microsoft services including Outlook, Minecraft and Xbox Cloud Gaming experienced widespread outages Tuesday, disrupting access for millions of users worldwide. The company said it was investigating the cause of the outage, which began early in the day and affected sign-ins and online gameplay across multiple platforms.

Internet users were left in the dark Wednesday as problems with Microsoft services triggered widespread outages across popular sites, like Xbox, Kroger, and Starbucks. Tens of thousands of users reported experiencing outages with Microsoft Azure, the tech giant’s cloud platform, Wednesday afternoon, according to DownDetector.

In the midst of an outage, Microsoft’s CFO reported that its Azure revenue growth was hampered by a capacity shortage that will continue throughout its fiscal 2026.

Microsoft's AI infrastructure spending to meet growing cloud services demand is outpacing Wall Street expectations, deepening investor fears about the costs of sustaining the boom.
