The lemmy.world bubble

I'm noticing that new posts, comments and especially updates to posts and comments and votes are not pushed to the origin of communities which lemmy.world users have subscribed to. Or at least it takes many (>> 10) hours.

Just pick a random community that is not local to lemmy.world and compare the local copy with the origin. I would be surprised, if you don't find tons of comments from lemmy.world users which have not been pushed yet.

The result is a lemmy.world bubble in which lemmy.world users see posts and comments from each other but nobody else does.

Did anybody else notice this?
What is causing this?
How can it be fixed?

Yeah I noticed it too. I moderate communities on multiple instances so it's really bad for me
- /c/mmorpg@lemmy.ml is actually a community I'm subscribed to which has this issue. /c/guildwars2@lemmy.wtf is another example.
  
  And the thing is that I don't find how to repare it. I looked if the instances were defederated, but they are not. Lemmy.world respond and send data fast, and the others instances too, except if it's between lemmy.world and others. I tried with a alternative account to post on lemmy.ca from lemmy.ml and it didn't have delay. I just don't understand at all
  Edit : I have a hypothetis. Lemmy.world is still on 0.17 but the other instances are on 0.18. Maybe it have more consequence that we would think not being on the same version

@ruud@lemmy.world Is there anything we/you could do about this until 0.18.1 is released with support for Captchas?
- We're troubleshooting why this happens now. I'm not sure 0.18.x will solve the federation issue.
  
  I understand that 0.18.x has better/automatic worker_count scaling which should improve things. But it does not address protocol (overhead) issues like the number of ActivityPub messages sent across the Fediverse for a tiny change or a vote. I asume we will need some sort of bulk update between larger instances at some point to handle the increasing number of users.
  
  @ruud@lemmy.world Whatever you just did ... was good! I'm noticing that (changes to) posts and comments are now pushed much faster than before.
  @VioletteRei@lemmy.world Are you also noticing a difference?
  Also, Captchas have just been merged to LemmyNet/lemmy:main ➡ https://github.com/LemmyNet/lemmy/pull/3289
  And the first Relase Candidate 0.18.1-rc.1 has been tagged. 🙂
  Well, it was fun while it lasted. The bubble is back. It's like being diconnected from the rest of the fediverse ...
