Degraded Snippet Publishing Performance
minor Observed active window 3h 4m

View incident details and source

Snippet Building
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.
