Updates from Optimizely 3
- investigating
We are investigating an issue causing delays when publishing experiments and other changes. Customers may see deployments remain in an "Uploading to CDN" state longer than expected before becoming available. Existing experiences continue to serve normally. Our engineering team is actively investigating the cause and working to restore normal publishing times.
provider
- identified
We have identified the cause of the delayed publishing issue. A surge in snippet upload activity created a backlog in our processing queue, which resulted in extended "Uploading to CDN" times for some customers. Mitigation actions have been taken to stop the source of the backlog, and our engineering team is actively working to restore normal processing times. Existing experiences continue to operate normally. We are closely monitoring recovery and will provide further updates as progress continues.
provider
- resolved

The issue was caused by a temporary backlog in snippet upload processing, which has been cleared. We apologize for the disruption and appreciate your patience while we worked to restore service. Existing experiences remained available throughout this issue.
