I had a 6TB server with them at DC 16 and I was very happy with performance. I saw on reddit one seedbox provider say that in his experience servers with iNIC perform much better. I only had that one server with them so I cannot compare, but it would do 100MB/s up/down at any time. I had exact same specs as this offer : https://robot.your-server.de/order/market#558449
Single thread to my home about 3000km away always maxed out my 100mbit line, while my current online.net fluctuates from 2-9MB/s. It also did a bit better overall on torrents, if it weren’t for 20TB limit I wouldn’t trade it.
There is a lot said about “bad peering” with Hetzner but in my experience it’s the best I used after Leaseweb.
