## Summary

Microsoft says it is investigating elevated infrastructure load across several regions, which is causing connectivity problems for multiple Microsoft 365 services. The regional scope helps explain why users could face disruption across work and communication tools, while some were also unable to access the service status page.

Potentially affected services include Exchange Online, Teams, SharePoint Online, Microsoft 365 Copilot and Defender XDR. Microsoft said it was restarting and repairing parts of the infrastructure, checking whether an increase in a specific type of service traffic was adding to the load, and considering redirecting traffic to other infrastructure; reports indicated both business and individual users were affected.
