The watches don't need the server to function (I'm wearing one), which seems to satisfy what you are saying.

I think the only major impact is that "coached" activities won't be available, but everything else in the watches works without a network connection. Data history isn't hugely available on the watch either, but that's just an inconvenience.

same. All of the data should still be stored on the watch and the app, since that works local via Bluetooth. Sync to other services like strava or trainingpeaks should happen once the services are online. Even the external sync on the watches should work, i just updated my deezer playlist on my epix 2 without issues and with connect down.

It might be annoying, but it still works. Without a note in the app, i would not have noticed.
