 * Uncordon Machine

 * “Cordoning” a Machine refers to disabling its services, so the Fly Proxy won’t route requests to it. In flyctl this is used by blue/green deployments; one set of Machines is started up with services disabled, and when they are all healthy, the services are enabled on the new Machines and disabled on the old ones.
