If the secondary data center, which houses the Unity server with the standby sequencer, fails there is a low availability impact. Applications connected through the primary data center are largely unaffected. There may be a small number of request errors in limited situations, but the majority of users in the primary data center do not notice the failure. Users connected through the Unity server in the second data center are disconnected. These users can immediately reconnect using standby IP addresses or another redirect mechanism. No operator action is required for Unity or Loader to react to the outage.
