GitHub Webhooks outage intermittently impacting redeploys

Update timeline

1. investigating Mar 09, 2026, 03:58 PM UTC

   We are seeing intermittent issues where preview builds and redeploys are not being triggered automatically. This has been traced to an ongoing GitHub webhooks degradation that is affecting a subset of webhook deliveries. While this issue persists, some documentation changes from commits or pull requests may not deploy automatically. Customers can trigger a manual redeploy to publish updates, or contact support for assistance. You can monitor GitHub’s status here: https://www.githubstatus.com/

   GitHub has resolved the webhook degradation. Preview builds and redeploys should now function normally.
