 It is strongly recommended that your client program has retry logic so that it could reestablish a connection after giving the transient fault time to correct itself.  We recommend that you delay for 5 seconds before your first retry. Retrying after a delay shorter than 5 seconds risks overwhelming the cloud service. For each subsequent retry the delay should grow exponentially, up to a maximum of 60 seconds.
 
 For code examples of retry logic, see:
