Suppose one way around it would be to rent a cheap VPS in the UK and piggy back off the connection?
Otherwise, there’s a s2 ‘NORDiC’ version going around which is actually in English audio - just with various scandiwegian soft subs, so it’s defo out there. DM me if you still struggle to find it.
Don’t forget, you can also use SRV records to point a domain to another target, where you can also omit the port number. So connecting to server.org say, can point to mc.server.org:25565 under the hood.
This prolly isn’t what hypixel are doing as everything’s likely on the same network and their router/firewall is just forwarding traffic onto different machines, but SRV is one way to redirect a minecraft connection (and you could combine the technique with subdomains).
