The best thing to do is to [attempt to] block the attacks, by using a proper firewall and monitoring your traffic properly, then firewall banning the IPs and whatnot what you see are spamming connections, etc. I don't think there's anything any SA-MP staff members can do to help you.

Or, the best course of action may to be contact your server host, it depends on who you're hosted by and their support.
