Key points
- Microsoft 365 server outage causes widespread international transport disruptions
- Deutsche Bahn faces delays in sending timetables for diverted rail services
- Exchange Online and Windows 365 Cloud PCs impacted globally
A major technical failure affecting Microsoft 365 and related cloud services has disrupted railway operations and communication systems internationally. In Germany, national rail operator Deutsche Bahn experienced severe slowdowns with Microsoft Outlook starting at 7 p.m. on November 12, attributing the malfunction to underlying problems in Microsoft's server infrastructure.
The disruption hindered the transmission of schedules for diverted routes—an issue worsened by ongoing network construction work. While overnight freight traffic bore the initial brunt, uncertainty remained regarding potential spillover into daytime passenger schedules. Similar communication failures surfaced globally, with Australian media noting an unnamed operator struggling to dispatch trains due to email failures, and Canada's Via Rail reporting that customer alerts regarding delays were blocked, though core transit movements remained stable.
Microsoft acknowledged the service degradation across enterprise and consumer tiers, noting that certain servers brought back online subsequently froze again. Affected platforms included Exchange Online, web and desktop versions of Outlook, and Windows 365 Cloud PCs, highlighting vulnerabilities in relying on centralized cloud infrastructure for critical public transport logistics.
