(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
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?
Thanks, this might be on to something because I don’t see a sh.itjust.works post on the lemm.ee version but I know beehaw defederated from them, and the community is a beehaw community. Maybe lemm.ee is pulling from beehaw.
But I don’t think it fully explains the situation. Here’s the post on beehaw:
https://beehaw.org/post/528754
For me that shows 17 comments, and I only see 13 on lemm.ee. But lemm.ee is defederated from fewer instances than beehaw, so what could explain that?
Edit: is it possible lemm.ee is simply not aware of all the instances?
You can see exactly which instances are federated or blocked from an instance by going to the instance with /instances. So for Beehaw it’s https://beehaw.org/instances and for lemm.ee, it’s https://lemm.ee/instances. It looks like they’re both federated to each other.
Is there a way to see what instances any given instance is defederated from? Or to see what instances any instance has defederated themselves from?
The structure of all this makes my head hurt lol. But I think I’m figuring it out…
You can click “Instances” at the bottom of the page on lemm.ee to see what lemm.ee has blocked. But I don’t know how to tell what instances have blocked lemm.ee.
I see the linked instances but not the blocked ones. I think the thing that was confusing me is the search results not showing me communities that I know exist on other instances, even when the filter is set to “all”… I’m sure that will be ironed out over time, though
Oh, by the way, 100% it is. Beehaw has the true version, so everything is pulling from there.
