DatacenterServingStatus

Whether a datacenter currently has a ck-api instance able to serve clients. Three-valued on purpose: "nothing is serving there" and "the liveness signal could not be read" look identical through a boolean and call for opposite reactions.

enum DatacenterServingStatus {
  SERVING
  NOT_SERVING
  UNKNOWN
}

Values​

DatacenterServingStatus.SERVING​

At least one instance in that datacenter has heartbeated within the freshness window and is not draining.

DatacenterServingStatus.NOT_SERVING​

The signal was readable and reported no instance able to take a client there. An app placed here would be created and stored correctly, and its players would be told the app is temporarily offline until an instance returns.

DatacenterServingStatus.UNKNOWN​

The liveness signal itself could not be read or trusted. Must NOT be presented as an outage: a fleet-wide heartbeat failure once made every datacenter look dead while all of them were fine, and healthy players were told their app was offline.
