 ### Considerations
 
 Applications that are deployed in a zone-redundant App Service plan continue to run and serve traffic even if multiple zones in the region suffer an outage. However it's possible that non-runtime behaviors including App Service plan scaling, application creation, application configuration, and application publishing may still be impacted during an availability zone outage. Zone redundancy for App Service plans only ensures continued uptime for deployed applications.
