From Sunday 2025-11-16 02:00 UTC to 2025-11-16 03:00 UTC we will be conducting an engine upgrade of our database responsible for API & User authentication. While we have taken steps to minimize disruption, we anticipate up to 20 minutes of degraded performance during this window.
The Buildkite Dashboard and APIs will be unavailable during the downtime period, and no new work will be scheduled during the downtime. Agents which already have work can run the work to completion, but agents will not be assigned new work and will not be able to submit the results of work until downtime is completed. Webhook requests will not be acknowledged during the downtime, existing webhooks will not be processed until downtime is completed.
In the unlikely event of service disruption beyond 20 minutes, we will promptly update our status page advising as such.
