A Microsoft Cloud outage has impacted millions of computer systems globally. Users reported sudden shutdowns or restarts of their systems, which Microsoft attributed to a recent CrowdStrike update. According to Microsoft's Service Health Status updates, the preliminary cause is a configuration change in part of their Azure backend. This change disrupted the connection between storage and compute resources, leading to connectivity failures.
