Review comment:
The issue is when the Manager is not an active service (initialization
hasn't been completed) because it is still in the process of upgrading. Not due
to an error of some kind. the isActiveService only checks for a boolean inside
manager that gets set to true when it is determined that it has completed
initialization.
