Published: December 15, 2017 Problem
In Platform version 8.1.0 and later, if you only have a single instance of an application’s UI component deployed on your Platform and you move the component through the SOC, there may be a brief period (a few seconds) of downtime for the application until the new workload is deployed. Note that scaling an application through the Developer Portal will not cause downtime in this way. Resolution
To avoid possible downtime, and follow best practices for high availability, have 2 or more deployed instances of an application’s UI component on your Platform.
