Issue Status: RESOLVED
Issue Description: Some users may experience intermittent access issues in OneDrive for Business.
More Info: Affected admins and users may also be unable to upload photos, and they may inadvertently see initials or a people icon instead of the user’s profile photo.
Final Update 31/01/2025 12:23:00 PM – Microsoft have successfully redirected traffic to alternate infrastructure and deployed a supplementary fix to the affected environment, and confirmed after a monitoring period that impact has been remediated.
Scope of impact: : Impact was specific to any admin or user served through or located in the affected infrastructure.
Root cause: An unexpected increase in traffic caused a section of infrastructure, that facilitates access to OneDrive for Business, to perform below acceptable performance thresholds and cause impact.
Next Steps: Microsoft are analyzing performance data and trends on the affected infrastructure to help prevent this problem from happening again.
