In my game servers experience, I had to close my gaming community for a while due to DDoS Attacks. I usually received DDoS from booters free and paid both and the IP's were usually from China, I tried blocking them but before the firewall would drop it would already saturate my internet connection. For VPS, I straightly went for OVH and it is keeping me well up for now.
A question i would like to ask everyone
I'm receiving DDOS Attacks on my VPS, I receive notifcation your IP is under attack and all. But only my TeamSpeak3 server goes down, VPS works fine, Internet speed is fine, No RAM or CPU saturated. What i can do about this?
