Current Status: Engineers are continuing to coordinate with the affected third-party Content Delivery Network (CDN) to resolve the issue. Simultaneously, engineers are investigating potential alternative content and network routing options to remediate impact.
User Experience: Affected users are unable to access the Yammer service from China. As a workaround, users may be able to connect to the service using Windows Phone, Android, or iOS Yammer apps.
Customer Impact: Customer impact appears to be limited at this time. Engineers have identified that impact is limited to users connecting from China.
Preliminary Root Cause: A third-party Content Delivery Network (CDN) used to serve static page assets is inaccessible.
