There are instances that federate together as a single sort of entity.
So, are there other entities? Meaning, is there a group of Lemmy instances somewhere outside of the existing ones we see here?
And, how do I get there, and which one don’t have people from the USA?
Edit, image example
I don't think that exists, but you might be interested in what Bonfire calls "archipelago mode". It's where instead of open federation being the default, an instance deliberately federates with selected other instances, which can result in a small group of instances cut off from the rest.
