This is still ongoing today (as of the time of this comment).

I created a comment on lemmy.ml to a posting on lemmy.world and it never made it to lemmy.world or another instance I have subscribed to the community. It has been over an hour:

My lemmy.ml comment: https://lemmy.ml/comment/691998

Is not appearing on the posting at: https://lemmy.world/post/179458

Another subscribed instance is also not getting it: https://bulletintree.com/post/4487

I think people moving to smaller servers is actually adding a different type of overload, as federation is falling over when there are over 100 peers… the more popular a topic, the more peers have subscribers and that creates a big federation replication load.

As far as i can tell, there is no protocol for server integrity checks to find missing replication of comments/posts, nor is there a backfill protocol or logic to repair replication.

Is there a workaround for this?

First, you have to have a active subscribers on both servers you are looking at, and then from that time forward they are supposed to federate content.

I have tried adding new new nested comments, edits to my own postings and comments to try and “workaround” the problems, but it isn’t always an option and I haven’t found a reliable way to get servers to heal their copies of missing content.

@nutomic@lemmy.ml @dessalines@lemmy.ml

I’m having trouble with this too. I mod !usmlr@lemmy.ml from both here and lemmy.world.

I can’t even see the community here directly anymore!

But using the federated URL to itself works

Comments are also not federating fully. From here this post, created from lemmy.one, has 6 comments

But from lemmy.world it has 5

And this post https://lemmy.ml/post/1226483 viewed directly from lemmy.ml shows 13 comments, but I can only see 9. For both the community settings and my own user settings I have all languages selected, so it shouldn’t be a language filter problem.
