Let’s say we have lemmy instances A, B, C.

alice from A makes a post “Hello, world” to B. What happens? How is it processed on servers A, B, C and how do users from A, B, C receive her post?

    Do you mean that the database is not identical, but still duplicates all data, basically? (you said “they each have a copy”, I assume it’s persistent on disk). So if we have 100 lemmy instances, they all save the same post.

      Correct. Each server that shows the post to its users stores a copy of the post. It does not necessarily store attached media (IIRC Mastodon usually does and Lemmy usually hotlinks media).
