I'm no good at typical prepper activities like constructing a shelter or stockpiling food. But I can at least play at being a digital prepper by, say, setting up a mirror of the Debian archive. These days, that's doable for individuals with a high-speed (e.g. fiber) Internet connection and a few hundred dollars to spend on storage. The trick, of course, is to make sure that the project isn't wasted, since I'm consuming substantial bandwidth from another mirror at least on the initial pull.
