Una interrupción de Microsoft que comenzó alrededor del mediodía, hora del Este, el jueves 12 de noviembre, dejó fuera de servicio Outlook, Teams, Copilot y otros servicios de Microsoft 365 para usuarios en docenas de países.

Este análisis detalla qué se dijo y cuándo, y las preguntas que una revisión abierta podría responder.
