Incident Report - API Outage on December 2, 2025

Incident report for DatoCMS

Dates & times in UTC.

Resolved

On December 2 at 13:13 CET, our API was unavailable for 9 minutes during a deployment, causing errors when accessing the CMS interface.

What happened

During a routine database migration deployment, code that depended on a not-yet-created database table was accidentally included. This caused the API to fail until we identified and rolled back the changes.

Prevention

We're implementing stricter code review checks to ensure migration-only deployments don't include dependent code, and adding automated tests to catch this type of issue before deployment.

We apologise for the disruption and appreciate your patience.
