Completely isolate local controller from DNS from cloud

Local controller are supposed to designed to work without cloud. However it is found that last week when cloud DNS down, local controller also down for no reason. There’s a way or workaround this, but I believe strongly that local controller should be in default isolated from any cloud service. Please make a button or something to implement this https://help.alta.inc/hc/en-us/articles/47983555191067-Using-Alta-Control-in-an-Isolated-Offline-Environment by default for local controller.

Would love to see this get some traction…
