Starlink relies on starlink downlinks of course, I assume they'd degrade quickly, do they have generators, and what internet would there be to connect to. But I am independent of the grid for a week at least. There would be a transition period for society. I kind of regret not spending the bigger money for full house solar with battery backup. Then I'd really be in good shape for the end of the world, except for running out of food. And someone coming in and taking it away from me.
