It's the same with relays. Everything in Germany.

my relay is in Sofia... one of the most densely connected cities in the world, probably half of the IT industry helpdesks are located there
btw, as far as places to run relays in europe goes, bulgaria is probably number one, with the least laws about speech and their enforcement of copyright is very lax too, once in a decade maybe since the end of communism they banned one song that was insulting to villagers, it's a pretty song, "idem ot selo" https://www.youtube.com/watch?v=NCFIP3mMkL8 first line is "i am the greatest RNB artist"
Not exactly the same.
In the fediverse (activitypub) the user is tied to just one server.
In nostr the user publishes in several easily replaceable relays.
