Title ... I posted about this previously here (https://lemmy.ml/post/10395138).

The community "tenforward" on lemmy.world seems to have ceased federating around 5 days ago (which could be in line with the 19.2 update on lemmy.ml?).

No posts are coming through onto lemmy.ml (and yes I subscribed well before this).

Here's the lemmy.ml mirror: https://lemmy.ml/c/tenforward@lemmy.world?dataType=Post&sort=New

... and the lemmy.world "home": https://lemmy.world/c/tenforward?dataType=Post&page=1&sort=New

For comparison, here is the lemm.ee mirror, which is also on 19.2 and seems to be receiving posts just fine: https://lemm.ee/c/tenforward@lemmy.world?dataType=Post&sort=New

If it's relevant, comments are federating back to lemmy.world. I tried commenting on one of the (older) posts from lemmy.ml and it federated over to lemmy.world fine (here's the lemmy.world mirror of the comment: https://lemmy.world/comment/6699443). I haven't tried posts because they might be annoying.

Seems to be weird but drastic bug. Could be a weird edge case that was arbitrarily triggered by the looks of it?

EDIT (further information)

As a point of comparison, here's a random community on lemmy.world I found (which I think is new as I sorted by New in the community search) which is federating fine with lemmy.ml: https://lemmy.ml/c/noshitsherlock@lemmy.world

Additionally, regarding the test comment I mentioned above, subsequent replies have since flowed through to lemmy.ml just fine: https://lemmy.ml/comment/7387000

... and mirrored accurately on lemmy.world too: https://lemmy.world/comment/6699443
