On February 25, 2026, a recent deployment to our publishing app introduced a bug in the scheduling interface. Specifically, a code change caused an infinite loop that crashed the page when users tried to set a custom date and time for a post.

Customer Impact

If you tried to schedule a post using "Set date and time" during this window, the page would crash. Posts that were already scheduled continued to publish normally, and other features weren't affected. The issue lasted about an hour and fifteen minutes.

Steps to Resolution

We spotted the issue quickly through customer reports and confirmed it was tied to a recent deployment.

We rolled back the deployment within minutes, added a temporary deployment freeze to prevent further issues, and confirmed the scheduling feature was working again before marking it resolved.

Key Learnings

The rollback was fast, but we want to get better at catching these kinds of issues before they reach customers.

We're reviewing our testing and deployment process to see where we can add safeguards - like catching rendering loops in pre-deployment checks - so similar bugs don't make it to production.
