I’m sorry you’re getting downvotes. I’m betting the bulk are because you’re in c/askscience saying you don’t have any evidence to support your question, but that’s kinda the whole reason to ask a question. You weren’t speculating in a top level comment so I think it’s rude to be downvoting. As far as I can tell you’re asking genuine questions which is kinda the whole point of this community. Fuck the haters, ask questions when you’re curious!
Not OP but loss of the Pi results in loss of network connectivity. A headache if you’re home and never doing anything time-critical on the network. A disaster if you or anyone else is dependent on the network for anything time-sensitive (virtual doctors appointment, work call, etc), or you’re away from home and unable to directly VPN to your router to reconfigure DNS settings.
