Microsoft outage: Faulty health check took down email and Teams globally

A Microsoft outage disrupted email and Teams services for users, triggered by a faulty health check that caused servers to shut down in a cascading domino effect, with a slow recovery process underway. The health check caused servers to report themselves as unwell, rerouting traffic and overloading others in a vicious loop. Microsoft fixed it by pulling traffic, repairing servers, and gradually restoring access, attributing the issue to a network capacity upgrade. Everyday users likely cannot claim compensation due to unfriendly terms, but business customers with service level agreements may see remedies. The incident highlighted reliance on cloud systems, with experts noting data sovereignty concerns and the practical need for major providers.
