Ok ok… So me using Lemmy.world is a specific instance of Lemmy, so it’s almost like its own server? And other instances (maybe lemmy.unitiedstates?) is its own federated instance likely related to just U.S. posts and it can communicate with other instances? Do de-federated instances have no other communication with instances?
Apologies if these are silly, I feel like a dum dum because everyone else seems to grasp this except me.

When you use Gmail to send an email to Outlook, those two servers are federated.
Defederation blocks communication between servers.
