official update →### Summary On October 14, 2026, between 12:12 and 15:08 PDT \(19:12 - 22:08 UTC\), builds and deploys across all regions failed to start, stalled, or were significantly delayed during two periods of impact totaling about 2 hours and 20 minutes. The cause was a database schema migration run as part of a planned version upgrade of our internal job scheduler that coordinates builds, deploys, and other critical platform operations. The migration led to high load and a longer-than-expected recovery time of this system’s database. We will change how we perform upgrades and modifications of this system in a highly available fashion in the future so that a similar change cannot cause an outage again. ### Impact There were two periods of impact. During this time, live user services were not affected, but builds and deploys across all regions failed to start, failed to finish, or were significantly delayed. **Period 1: 12:12 - 12:40 PDT \(19:12 - 19:40 UTC\), about 28 minutes** * New builds and deploys did not start. Deploys in progress stalled. * Some requests to create a deploy through the Dashboard, API, and CLI returned errors \(HTTP 500\). **Partial recovery: 12:40 - 13:18 PDT \(19:40 - 20:18 UTC\)** * Builds and deploys ran, but deploys took about 20 seconds to start instead of a few hundred milliseconds. **Period 2: 13:18 - 15:08 PDT \(20:18 - 22:08 UTC\), about 1 hour 50 minutes** * Builds and deploys were delayed, stalled in progress \(including in pre-deploy\), or failed. From 13:51 PDT, almost no new builds were able to start. * Some queued deploys did not start after recovery, and cancelling them through the API had no effect. Users needed to retry these deploys. ### Root Cause Render uses an internal job scheduler system to coordinate builds, deploys, and other critical platform operations. We were rolling out improvements to how it distributes work, and began a planned version upgrade of this system in production after a successful practice run in a
