US20150135268 - System and method to improve network security
Embodiments of the present invention enable an organization’s system to disavow false network load/traffic from overwhelming its servers. The system includes a processor, and a memory having instructions executable by the processor to determine load on its network.

This may allow the legitimate clients of the system to follow the shadow server and enjoy the services. However, the illegal clients may not be able to predict the new location of the shadow server and thus may not harm their targeted set of services.
