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.
More people should use BiglyBT and its Swarm Merging feature. You get the ability to seed or download chunks from peers across separate torrent files.
It’s a shame because if more people used it, the BiglyBT devs might add hash-based merging (with v2 torrents) instead of just size-based. Hybrid/v2 merging is still possible, but file size is less reliable and caters to files only larger than 50MB.
Some kinda auto v1/v2/hybrid private<->public torrent maker plugin for BiglyBT would be… bigly.
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).
