There are virtually no unconnected places in most of Europe yet wilderness is still dangerous. It is good that rescue services can help you if accident happens (and it can happen even to the adequatly prepared).

The location, despite not being remote, has NO connectivity. It's the closest thing I can think of in my proximity that is completely unconnected. You're lucky to get GPRS there in terms of data, and most likely you won't even be able to place a call.[1] There is no broadband/fibre or any other sort of physical network connected to the buildings in the area.[2] The only way of connecting the place aside from Starlink that I've found is other satellite options[3], and it's most likely going to be 6 times as expensive and 50 times slower.
