Being the biggest Minecraft server in Finland does come with a price. Usually we do not get DDoSed hard but this time we got hit with over 2 Gbps of traffic per second. Hetzner null-routed our main server and we have a support ticket pending so we can get it up and running again. Players are angry and moderators too. What should I do to prevent this in future? One thing that comes into mind is dropping all traffic on server query ports which use UDP, maybe there is even a way to throttle the traffic on specific ports. It would probably be a good idea to buy high availability pack from Hetzner, or even change provider if we start getting this frequently. I know that there are a few Minecraft server admins here who have, unfortunately, had to deal with DDoS. Want to help me and give some advice? What do you think about my ideas? Will it help my server? Thanks everybody.
