这里看到他们的备注：
* All servers are DDOS PROTECTED!
That includes BASIC ddos filtering/mitigation using our multi-gigabit ddos protected network, equipped with the latest technology in order to identify and deny the dos/ddos traffic before it reaches your server and disrupt your normal traffic.
IMPORTANT: Keep in mind that this service protects our whole network and clients, and in NO way will specialize in protection of single clients that become frequently target of ddos attacks. In the latter case, you will have to purchase a more advanced and sophisticated security package (ex. managed dedicated firewall based on Juniper NetScreen hardware) in order to be protected.

似乎如果攻击太频繁还要加钱才给保护
