In the Mixer, the tool that allows you to operate your Live Broadcasts of the type 'Production', you have an indicator about the status of the Live Broadcast.
This information will let you know, for example, if the servers in the cloud are already available (started / not started) to execute all audio and video mixing operations.
Not started: the Live Broadcast one is not up and we can not transmit yet.
Initializing: the Live Broadcast is in the process of getting up and we still can not transmit.
Initialized: the Live Broadcast is up and we can start transmitting.
