1. A method comprising:
detecting an attack event targeting a customer network resource;
determining a routing scheme that routes network traffic to one or more mitigation systems of a mitigation network;
communicating the routing scheme to one or more routing devices to cause the one or more routing devices to update from a first Domain Name Service (DNS) zone associated with a non-mitigation system of the mitigation network to a second DNS zone associated with the one or more mitigation systems;
determining one or more properties of any one or more of the following: the attack event, the mitigation network, and the customer network resource; and
causing the network traffic to be routed to according to the routing scheme,
wherein the routing scheme is selected based on the one or more determined properties.
