A service coordinator in the first data center is notified about the master switch. The service coordinator notifies each instance of the first service that the first service is not a master. Each instance responds with an acknowledgement. After it is confirmed that all instances of the first service have responded with an acknowledgement, a client coordinator in the first and/or second data center is updated to indicate that the second service is the master so that clients may send requests to the second service. Also, a service coordinator in the second data center is notified that the second service is the master. The service coordinator notifies each instance of the second service that the second service is the master.
