Here’s another one of the big ones, in my opinion; it says a lot more about the actual machines.dev

If this is the number of Machines simultaneously existing (as opposed to the number of starts or creations), then a person does need to contact Fly.io if they want ≥20 (or so).
Some posters in the forum have mentioned having a thousand running at once, so this other limit is more of a question of the platform requiring notice in advance…
