This is not a prediction. It is a scenario exercise. We describe what would happen, hour by hour, if a typical 30-person European professional services firm lost access to its US cloud provider overnight. The firm runs on Microsoft 365 with Azure AD, Exchange Online, SharePoint, Teams, and OneDrive. It has no documented exit strategy.
The purpose is not to cause alarm. It is to make the dependency concrete, because most organisations cannot articulate what would actually break until they walk through it.
