Microsoft (MSFT, Financials) faced a major global outage that disrupted its Azure cloud service and Microsoft 365 suite, affecting airlines, telecom companies, and other critical industries. The company said the issue stemmed from a configuration change in a portion of Azure's infrastructure and has since been largely mitigated.

Outage tracker Downdetector reported over 18,000 Azure issues before falling to 3,300 by early afternoon U.S. Eastern time. Teams, Outlook, and other productivity products in Microsoft 365 saw user reports drop from nearly 12,000 to under 4,000 as systems recovered.

Alaska Airlines, Vodafone, and Heathrow Airport in the U.K. reported Azure-related website and system difficulties.

Microsoft said that Azure Front Door, a worldwide content and application delivery network, and its Azure management interface were affected. In an update, the business stated customers may again access the Azure management interface directly, however some endpoints may still have difficulties.

The setback follows a similar Amazon Web Services (AMZN) outage last week that affected Snapchat and Reddit. The back-to-back disruptions show how dependent global infrastructure is on a few huge cloud providers.
