(Please correct any misunderstandings below.) From my limited understanding of the fediverse, for each thread that exists, every instance will host its own version of it. This instance-specific version will collect comments left from users from all instances in the “world” (whatever that means here). The exception is if instances block other ones.

But what about this random thread:

https://sopuli.xyz/post/683221

https://lemm.ee/post/30817

The first is the original (which is confusingly posted in a community at Beehaw, but I believe the original is at sopuli.xyz because the user is registered there). The second is the version on lemm.ee. Why do I see 13 comments for lemm.ee and 18 for sopuli.xyz? One comment that I do not see on lemm.ee is by a user on sh.itjust.works. This is not a blocked instance. Is it because lemm.ee needs to pull from all instances periodically, and this is just a cached version? If so, how often are these updates, and is there any way to see a timestamp of the cache for an individual post?

    I’ve been seeing this quite a lot today and it’s also probably because I’m looking out for it. The posts I’ve seen and checked all had comments from users from Beehaw, Lemmy.world, kbin. The comments did not match up between viewing from here (lemm.ee) and the source post. I’m kinda putting it down to all of these instances getting hammered with signups and potential strain on the servers but I’m happy to be told that’s wrong.

    I would guess that things will get better, sync faster and more consistent as time goes on.

    If anyone has a better or more informed opinion as to why this is happening please comment as I’m trying to get a better understanding of all of this as the days go on.
