Does services published with ArcGIS Server work without internet connection?
I’m not sure if the services published with ArcGIS Server still work without internet connection.
If you lost your internet connection. You will be lost displaying your services by ArcGIS Java Script but you still can displaying the services by using ArcMap (Locally). Note that the connection must be localhost or the machine name.
Largely depends on what network you're talking about. ArcGIS Server can work without internet, (access to external resource outside of your network). If the Server machine loses connectivity to any network, (internet or intranet), then no one will be able to reach the machine nor access services.
Many thanks Abdullah and Jonathan,
But how can I still display services (with no internet connection) via browsers as ArcGIS JavaScritp fails to do so? Am I left with one option: to display them in ArcMap?
You will not have the base maps from AGOL but if you have ArcGIS Enterprise you can create your own base maps
