Microsoft is investigating an ongoing global outage blocking access to some Microsoft 365 and Azure services.
According to DownDetector, which tracks IT Outages Globally, Minecraft, Microsoft 365, Microsoft Teams, and Microsoft Azure are among the affected services.
Microsoft confirmed that the outage has impacted the following services:
| Impacted Services | Not Impacted Services |
| Microsoft 365 admin center | SharePoint Online |
| Intune | OneDrive for Business |
| Entra | Microsoft Teams |
| Power Platform services | Exchange Online |
Microsoft shared that the incident resulted from a buggy configuration change deployed by Azure backend workloads as Redmond explained:
“A backend cluster management workflow deployed a configuration change causing backend access to be blocked between a subset of Azure Storage clusters and compute resources in the Central US region,”
“This resulted in the compute resources automatically restarting when connectivity was lost to virtual disks.”
“Users who can access the impacted Microsoft 365 services may experience latency or degraded feature performance,” Microsoft explains on the service health status page.
“We’re analyzing traffic patterns within a section of a networking infrastructure to assist our investigations. Additionally, we’re reviewing mitigation options, including potential failovers, to provide relief.”
After acknowledging the outage Microsoft 365 Stated on social media:
“We’re currently investigating access issues and degraded performance with multiple Microsoft 365 services and features. More information can be found under MO842351 in the admin center,”
The last update at 18:13 UTC, a subset of customers may have experienced issues connecting to Microsoft services globally
“We are investigating reports of issues connecting to Microsoft services globally. Customers may experience timeouts connecting to Azure services,” Redmond says on the Azure status page.
“We have multiple engineering teams engaged to diagnose and resolve the issue. More details will be provided as soon as possible.”
Microsoft 365 customers experienced another severe outages in last week after a faulty CrowdStrike Falcon update also caused a widespread Windows outage, crashing systems with blue screen of death (BSOD) errors and impacting many organizations and services worldwide, including banks, airlines, airports, TV stations, and hospitals.
