Enterprise drone can't find license.drone.io

Drone enterprise cannot find the licensing server - appears there is no dns entry. Unfortunate that the licensing server going away causes an outage of the service.

error: "Post https://license.drone.io/api/v1/license/renew: dial tcp: lookup license.drone.io on ***.***.***.***:53: no such host"   
  level: "fatal"   
  msg: "main: invalid or expired license" ```

Exactly same error for our license today.

How have you fixed it?
