Trying to do a bit of detective work on the posts themselves -- it looks like recent posts aren't federating out to Lemmy? Your post has been up for 24 hours without federating to ani.social or lemmy.world or lemmy.ml or lemmy.dbzer0.com or reddthat.com (at least prior to making this comment). Some comments from lemmy.world made it to one of my posts (the rain one from ~5 days ago) including a back and forth with a response today (~10 hours ago), but those comments aren't federating to any other instances.
Hmm... I think something broke.
