I believe it’s related to the Azure outage: https://www.bleepingcomputer.com/news/microsoft/microsoft-dns-outage-impacts-azure-and-microsoft-365-services/
Microsoft is investigating an ongoing DNS outage affecting customers worldwide, preventing them from accessing Microsoft Azure and Microsoft 365 services. According to reports on DownDetector and social networks, this incident began impacting Microsoft's services almost 1 hour ago and is currently causing server and website connection issues for tens of thousands of users. Some of those affected are having issues accessing the Intune and Azure portals, as well as the Exchange admin center, while others report that Microsoft's Azure Front Door Content Delivery Network (CDN) service is also down.
