The thing is though, the instance your create a community from only really affects who you interact with to recover your moderation team if everyone goes poof. Otherwise the instance essentially serves as a vanity domain for the community (think email). It doesn’t matter if lemmy.world is down to me at all. I can still post to its cats community using my sh.itjust.works account just fine. Anyone that isn’t on beehaw will see my posts with or without the origin instance of the community being online (because beehaw is defederated with my instance).
you can still post to .world, but that post won’t leave your instance if .world is not up to boost it to every other instance subscribed to that community.
if you posted to a .world community from sijw while .world was down, i won’t see it until .world gets back up, gets the message from sijw (which will usually retry a few times before timing out), and boosts it to blahaj. except for cases like this where i’m replying directly to you all 3 instances need to be up for federation to work properly
