However @bnewbold pointed out, correctly!, that there were cheaper options available. If we used even Linode's block storage, it would be cheaper (but still expensive) for the storage component, and this is true https://bsky.app/profile/dustyweb.bsky.social/post/3lah5n3kld42q
In fact @bnewbold and alice had gotten the server down to just close to $200/month in their estimate, much much cheaper than I had, by choosing a dedicated server plan. Much cheaper!
But there's a problem though; that's cheap because you've got a server that has a dedicated disk...
