 Open Match rollout status can be viewed by navigating to the [global-game-open-match](https://console.cloud.google.com/deploy/delivery-pipelines/us-central1/global-game-open-match) delivery pipeline. Since open match is deployed onto a single services GKE cluster, deployments are automatically rolled out with no need for manual promotion.
