Latest Message<\/th>\nTitle: Affected users may be unable to access Microsoft 365 services and features<\/p>\n

User impact: Affected users may have been unable to access Microsoft 365 services and features.<\/p>\n

More info: Users attempting to access or use features within Microsoft Teams, Exchange Online, Microsoft 365 admin center, and Windows 365 may have been impacted.<\/p>\n

Final status: We\u2019ve identified that a portion of network infrastructure in North America was misconfigured, which caused traffic across the region to become unhealthy. We\u2019ve taken mitigating action to rebalance traffic in the affected infrastructure, and we\u2019ve observed service health improve to normal levels across all impacted services.<\/p>\n

Scope of impact: Any users in North America attempting to access the services listed in the More info of this communication may have been impacted.<\/p>\n

Start time: Thursday, October 9, 2025, at 6:10 PM UTC<\/p>\n

End time: Thursday, October 9, 2025, at 6:50 PM UTC<\/p>\n

Preliminary root cause: A portion of network infrastructure in North America was misconfigured, which caused traffic across the region to become unhealthy.<\/p>\n

Next steps:
– We’re analyzing configuration policies and traffic management processes on the affected network infrastructure to identify necessary refinements and increase resilience in the event of future incidents.<\/p>\n

We’ll provide a preliminary Post-Incident Report within two business days and a final Post-Incident Report within five business days.<\/td>\n<\/tr>\n
