If the ideal setup is many medium sized instances rather than a few huge ones, wouldn't that mean users would need to subscribe to duplicate communities in all of those instances? (sh.itjust.works)

Otherwise, if we have a lot of medium sized instances but the most popular communities are hosted on just a few huge instances, doesn't that defeat the purpose of distributing load across many instances?

If that's the case, how do we solve the cumbersome user experience of having to subscribe to the same community over and over again across a ton of medium instances?

So if a home server goes down will those posts disappear from the community server? And what if it goes down temporarily and not permanently, do the posts stored on the home server temporarily disappear?

So if a home server goes down will those posts disappear from the community server?

terminology wise, "home server of a community" and then there are remote-servers for that community. And Lemmy community/devs tend to call a "server" an "instance". To answer your question... if a user is on a remote instance from a community, they are reading copies of the content in a local database. If the community home instance goes down, the copies will still be there in the remote servers. However, they are now in an isolated island and none of the other servers will get the new post and comments - as the home instance of a community does distribution. There isn't any kind of warning indicator that you are on an isolated island.

Nothing disappears, but it is possible to have incomplete replication - have only some of the comments and posts and get an impression that nobody replied or that there isn't much content.

Got it, I understand this a lot better now - thanks for the detailed reply!
