How do you know if your server (e.g. lemmy.world) is federated with another server?
I want to see a list for each popular server (e.g. the top 10 lemmy instances) and I want to see - for each instance - with whom they federate. How can I do this? Any sure-fire way to know if a instance like HexBear.net is being federated with lemmy.world? How do you know?
