Microsoft 365, Copilot and Store outages hit thousands of US users

The simultaneous failure across productivity, AI assistant and storefront services is the notable detail here: Copilot's outage alongside Microsoft 365 suggests AI features remain tethered to the same underlying infrastructure as core office tools, so an AI selling point can inherit the reliability of the platform beneath it. The affected population is enterprise and consumer users alike, plus anyone whose workflows now assume Copilot is available. Whether Microsoft discloses a common root cause, and whether Copilot outages get counted separately from email and storefront disruptions, is the open question.
