 Yesterday, some Microsoft clients in the central U.S., including some airlines, were affected by an outage on its cloud service system, Azure. Microsoft's cloud service status page indicated the company had identified a preliminary cause. Some users may still be unable to access certain Microsoft 365 apps and services, including Teams video conferencing. The company was aware of the issue affecting a subset of customers. A Microsoft rep said in a statement, we acknowledge the impact this could have on customers and we're working to restore services for those customers.
