> Yeah, that was my thinking, but that it'd be recorded locally in the DB, so that someone imports a blocklist and then you don't need to fetch a thousand instances every time.

Sorry, poor phrasing, that was also my thinking. You could just keep a table of "instance, state, last_checked" and refresh that record if last checked was past some arbitrary threshold. Hell you could even do exponential backoff on checks with a counter column (reset the counter to 0 when the state is toggled). Would still allow for revival of dead instances (does that ever even happen though?).
