In the past several days, I've noticed that comments that I make on this instance to cross-instance communities started to take up to several hours to propagate to the community's home instance, and now do not seem to propagate at all.

I've noticed the issue on lemmy.world, lemmynsfw.com, and lemmy.ml. Several comments I made today in a programming.dev community went through more or less instantly, though.

Has anyone else noticed this?
