I have 2 GIS servers participating in a site with a web adaptor in front of them. Site A is the primary site and hosts both the web adaptor as well as the config-store and server directories. In this scenario if site A goes down will site B still be able to host clients?
If this is the case then is there any scenario to create a truly fault-tolerant ArcGIS server site, because the deployment scenarios all show the Data Store, Config-Store and server directories on a server, which it appears to suggest if that server is down then the entire site is down.
