I noticed many new individuals joining following the Reddit API news. Do you have any questions about this website, Lemmy, or the fediverse?

    One thing I haven’t been able to figure out from the official docs, is how exactly federation works with comments. Like, if my account is on instance A and I comment on a thread on instance B, is that comment stored/hosted on A, or B? If B, then what happens if A shuts down, does the comment stay up? Is it still attributed to my now-defunct account, or is the username replaced with “deleted” or something?

      From what I understand, all comments are hosted on their original server, but contain pointers that tell it what it’s parent comment is. These are then cashed to each viewing server. So if instance a goes down, to my knowledge someone viewing from instance b would still see it. But if instance C came along and never saw it before, it could never discover the comment. That’s at least my understanding, an actual Dev or someone more familiar with activity pub would give you a better answer.
