URL: https://github.com/apache/incubator-servicecomb-saga/issues/324#issuecomment-433776654
 
 
   for example，in workflow TCC Scenario
   ![workflow TCC Scenario](https://github.com/apache/incubator-servicecomb-saga/blob/master/docs/static_files/successful_scenario_TCC.png)
   when service2&service3 try() is success, then service1 begin confirm(), then alpha begin call service2 and service3's confirm(). but when service3 is down, how to ensure the integrity of this transaction? In this scenario, alpha will not reach the service3's instance anymore,and will nerver rollback the services'3 branch transaction. So, we need to find out a way to reach another service3's instance, that's why I raised this issue.
