The requests that were already in flight

Every rollout of `checkout` drops a handful of requests. The pods are healthy, the new ones come up fine, nothing restarts, and the endpoints are updated the moment a pod starts shutting down. Find what is costing the requests and fix it. Your change will be rolled out once to take effect, and the rollout after that is the one that is measured.
