I noticed a post on Lemmy.world that is having issues federating with PieFed.social on the AskLemmy@lemmy.world community:

I attempted to retrieve the original post. Which seemed to bring it over, except there were no comments attached to the post.

I attempted to retrieve the comments using the direct comment link, but PieFed would return a "post not found" error banner when entering that into the "retrieve remote post" field. I had read somewhere that this field could be used for comments as well . (Note this was all attempted before the post was eventually "locked").

Even an hour later there were a few more comments added, but on PieFed it is showing 4 comments, while viewing on Lemmy.world shows 25 comments.

Edit: I don't have any languages selected in my language settings, so I should be able to see all posts/comments regardless of the language.

Edit 2: Looks like 2 of the comments have now federated over (I don't think it's normal to take up to 2 hours for federation?). Still missing a third.... But now the original post looks to have been deleted.

Edit 3: updated with a new asklemmy post that isn't showing up on PieFed now.

Edit 4: updated numbers for newer post, that's 1 hour old now.

OP deleted their post in the meantime. It probably should have worked when you first tried to pull it, but a "not found" will be correct now.

Btw I don't know if comments get fetched. I think retrieving posts only fetches the post itself, not the attached comments.

Yeah, I just updated the post to point to a new one in asklemmy that isn't federating.

It looks like I should have been able to fetch comments using that retrieve remote post field as well, however that does not seem to be working:

Copy that link from the post/comment on lemmy and then paste it into the form on feddit and it should go fetch the post/comment for you and backfill it. A caveat is that votes are not fetched, so scores will just be at 1. Also, fetching a comment will fail if it is a response to another comment that hasn’t been fetched yet.

A quick example of what I see when trying to retrieve missing comments:

Lemmy.world had some issues earlier today but it has resolved itself now. Below is a graph showing up many activities lemmy.world had queued up to send to us.

The slopes are unusually jagged, normally when things get blocked up it's a smooth steady line. Maybe they were doing some configuration experiments.

When the cause is something at our end then it would effect all instances, not just lemmy.world.

Well, that definitely explains the issues I was seeing today. Thanks for sharing the graph!

Hi, where can I find this federation monitoring tool?
