UPDATE: This has been resolved as of August 19, 2023
I’m sure I sound like a broken record at this point, but is there any word on the federation issues between lemmy.world and Instances like fanaticus.social? Seems it’s been 3-4 weeks since posts/comments federated properly between those two.
I know there has been a lot going on over the last month, and this is probably low on the priority list, but I don’t think I’ve seen it formally addressed here.
You can always check what instances someone federates with - there’s an “instances” link on the bottom of every Lemmy homepage.
