for most vps companies as long as your server is online it is not their concern if you are being attacked on the operating system level
...in an unmanaged environment "it is your responsibility" to secure your server from threats like this.
the reason someone is able to do this to you easily can be found on your register page ... if you dont use any kind of security on your forms(ie captcha email validation test question botlist-blocking seperate databases for accounts etc)
this will constantly happen. and will be extremely difficult to manage as long as you have your mysql port open to the world or open to a service that allows unlimited consecutive connections like you do now (ie: your website and your computer )
you can view the people connected to your site ... I am sure that will show one or two ips making multiple connections to your register page blocking these hosts will "temporarily" help the issue
and tell you who it is.
as your host is now known as "able to be exploited" changing your ip address and securing your server more will "not" work. you should close your mysql port entirely for a while (at the very least) and setup your system to register and allow you access to the database in some other way

if he had low memory it would still load just very slow not crash ... you can host this game on a server with 512 mb of ram if you wanted ....also looks like his second example is from the account server
too many connections means simply that, "too many connections"
"shared networking" would not cause this either lol if someone had more than one server and had one system using up more bandwith than the rest it would cause the other systems to lag and lose connection not have extra connections
QOS settings resolve this issue and as far as i know any host would use such settings so that another vps in their network "couldnt" use up enough bandwith to affect the others in their network. (or they wouldnt have very many customers for long)

okay you dont need to restart your vps you can flush hosts, reset your connection, close port 3306 temporarily, or kill mysql and restart it to do this. Best option though would be to block the offending ip even if it is your own website for a while until the system recovers , cant make too many connections if they cant connect
you come back online after reset with nothing from before because with the connection overloaded the legitimate hosts(gameserver and accserver) are not connecting to be saved and are waiting in line when you reboot
also note : EVERY time you restart your server or mysql or do a maint you should repair your database to prevent dataloss (ie all is gone when you get back)
