There's some other issue with posts not propagating to lemmy.today. I'm not sure at what point this arose; I've only just noticed it.
I'm currently subscribed to !retrogaming@lemmy.world.
This is lemmy.today's view of that community:
https://lemmy.today/c/retrogaming@lemmy.world
The newest post to be visible is "Death Knights of Krynn [MS DOS] Intro on Creative Music System/Game Blaster", visible here:
https://lemmy.today/post/5957815
As of this writing, that post was five days old.
However, actually looking at the community on lemmy.world, there have been newer posts there. These have not propagated.
https://lemmy.world/c/retrogaming?dataType=Post&page=1&sort=New
As of this writing, there are four, the oldest of which is also five days old (so presumably, whatever caused the issue happened at least five days back, possibly exactly five days back). None of these have propagated to lemmy.today via federation.

The newer posts have propagated to some other instances that I have looked at, including lemmy.ml (0.19.3):
retrogaming@lemmy.world on lemmy.ml
feddit.de (0.19.2):
retrogaming@lemmy.world on feddit.de
feddit.uk (0.19.2):
retrogaming@lemmy.world on feddit.uk
Both lemmy.today and lemmy.world are reporting that they are federated with each other:
https://lemmy.today/instances
https://lemmy.world/instances
That is making me a little suspicious that whatever is broken is somehow specific to lemmy.today (and apparently an ongoing problem, not a one-off, since it's not just a single missing post).
I also have one request. Would it be possible to create a "lemmy.today community"? This could serve as a point for people to discuss or report issues on the lemmy.today instance (like this one). The closest thing we have right now is the "announcements" community, but post creation there is (understandably) locked for non-moderators. I'd do it myself, but I think that it'd probably be more appropriate were an instance admin the moderator. And while adding comments to this post is probably the best existing way to both notify you that there is an issue and make anyone else on the instance who might be experiencing the problem aware of it, I feel like most people aren't likely to go hunting into a recent update announcement to see if there are any issues on the instance or try to troubleshoot or help each other. I'd just message you directly with issues, but then other people can't see discussion or help or even be made aware that there is an issue.
On lemm.ee, there is such a community, with the name of !meta@lemm.ee.
I checked several other large instances, but wasn't able to find a similar-such community (I was looking to see if any convention had emerged as to what name to use for "discussion about the local instance"). I'm not sure that "meta" is the best term to use (I think it might be clearer to use the instance name or something, like !lemmytoday@lemmy.today, to make it clear that it's about the instance) but "meta" is short, and it has uptake from at least one instance.
Thanks.
Hi!
I looked and I can see the posts if I sort by New (default sort is Top Day I think):
https://lemmy.today/c/retrogaming@lemmy.world?dataType=Post&sort=New
That page has all the posts you mention above from the looks of it? Correct me if im wrong or if Im misunderstanding something.
And of course we can create a
lemmytodaycommunity, sounds like a great idea. A place to bring up issues about the instance. I agree with you about the name also. Meta doesnt sound good, and also its related to that Zuckerberg place... :)Hmm. I'm sure that I checked sorted by New.
investigates further
Okay, this is more confusing. It looks like what happens is that when I am logged in to lemmy.today, I cannot see the newer posts via lemmy.today. When I am not logged in, I can. That means that it can't be a federation problem, that something else is going on.
I've got no idea what would cause that. I don't have my account set up to block anything at all. I don't think that there's some kind of remote per-user blacklist or even if there were, any idea why I'd be on it.
considers
If there is some sort of blacklist, I assume that I wouldn't be able to comment there.
checks
It looks like I can comment in the community there just fine, and that a comment made on lemmy.today promptly propagates to lemmy.world:
https://lemmy.world/comment/7332440
Hmm. Well, now I am definitely puzzled.
If you don't mind me asking, when you viewed the page and were successfully able to see the newer posts, were you logged in to lemmy.today? I'm half-inclined to go create a second account on lemmy.today to see whether it is also affected, but if your account is impacted as well, that's at least one more data point, and then I'm not just creating throwaway accounts.
My understanding is that lemmy very recently got per-user instance blocking added as a feature -- kbin has had this for some time -- and I am wondering if maybe something might not be working correctly related to that. I can't imagine what else would cause the user account involved to be an input.
Thank you for looking at this.
EDIT: Maybe if there is something in the stack that caches generated webpages and those aren't being invalidated, since user might be an input there, but then...no, that can't be it, because I also don't see the newer posts in Jerboa.
Hi,
I just checked and I see the same thing both logged in and logged out. Try clearing your cookies for lemmy.today completely, maybe its something weird going on with those? They changed authentication code in 0.19-something.
My apologies. This may just be a combination of an error on my part and Lemmy not working as I had thought it worked.
There are two retrogaming communities, one on lemmy.world and one on kbin.social. I had thought that I was subscribed to both, but I was only subscribed to the one on kbin.social. lemmy uses subscriptions to determine whether to cause posts to propagate.
What I still don't understand is why being logged is a factor. I definitely could see the posts when not logged in, so they made it to lemmy.today.
I just subscribed with my lemmy.today account, made a post with another account (on kbin.social), then unsubscribed and made another post with that second account. Both posts were visible to my account.
So I still don't understand why being logged in is a factor for the earlier posts, but at the time that I was seeing the problem, I wasn't subscribed, and lemmy doesn't guarantee that propagation happens in that scenario, so I'm not going to complain about that.
thinks
Maybe when you browse a remote community not logged in -- since it's not possible for a guest user to subscribe -- lemmy fetches the posts directly when the community is viewed, rather then having them pushed to it. Otherwise, it wouldn't be possible to do much as a guest user with remote communities. And if nobody on lemmy.today was subscribed, that would explain the lack of popagation. That'd produce that behavior, where a guest user can see posts, but a logged-in user can't unless they're subscribed.
I don't know why different logged-in accounts would see different sets of posts, but.
Well, I'm sorry for bothering you. Probably just user error, and me being too ready to flag something as a bug after seeing earlier federation breakage. Thanks for your time.
Its ok, Im happy if you find a bug in Lemmy so we can report it to the developers. There are many bugs on their github issues page, so I wouldnt be surprised if you encounter some.. :)
