Microsoft Reference: SP990242

Issue Status: RESOLVED

Issue Description: Some users may experience intermittent access issues in SharePoint Online.

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 1:51:00 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 is specific to any admin or user located or served by the affected infrastructure may be impacted.

Root cause: An unexpected increase in traffic caused a section of infrastructure, that facilitates access to SharePoint Online, 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.
