The lemmy.world bubble (self.support)

9 comments fedilink hide all child comments
 

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.

Yeah I noticed it too. I moderate communities on multiple instances so it's really bad for me

/c/[email protected] is actually a community I'm subscribed to which has this issue. /c/[email protected] is another example.

[โ€“] VioletteRei 7 points 2 years ago* (last edited 2 years ago) (1 children)

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

[โ€“] necropola 10 points 2 years ago (1 children)

... or it's the federation_worker_count setting which is still too low on lemmy.world?

https://lemmy.ml/post/1216911

Though I think increasing this value is no longer required on 0.18.0 instances due to

https://github.com/LemmyNet/activitypub-federation-rust/pull/42

Which means that upgrading lemmy.world to 0.18.0 would probably solve this isuue, but I can fully understand why lemmy.world waits for Captchas to be restored (hopefully in 0.18.1).

[โ€“] VioletteRei 6 points 2 years ago

Hoping that 0.18.1 will not take too long

[โ€“] necropola 5 points 2 years ago (1 children)

@[email protected] Is there anything we/you could do about this until 0.18.1 is released with support for Captchas?

[โ€“] ruud 5 points 2 years ago (2 children)

We're troubleshooting why this happens now. I'm not sure 0.18.x will solve the federation issue.

[โ€“] necropola 4 points 2 years ago

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.

@[email protected] Whatever you just did ... was good! I'm noticing that (changes to) posts and comments are now pushed much faster than before.

@[email protected] Are you also noticing a difference?

Also, Captchas have just been merged to LemmyNet/lemmy:main โžก https://github.com/LemmyNet/lemmy/pull/3289

And the first Relase Candidate 0.18.1-rc.1 has been tagged. ๐Ÿ™‚

Well, it was fun while it lasted. The bubble is back. It's like being diconnected from the rest of the fediverse ...
