A method to mitigate attack by an upstream service provider using cloud mitigation services. An edge detection device, which located at the subscriber's network edge, is able to communicate information via status messages about attacks to an upstream service provider. The service provider is then able to mitigate attacks based on the status messages. There is a feedback loop whereby the amount of dropped traffic by the service provider is added to the network traffic to keep the mitigation request open and prevent flapping. Likewise, the detection device includes time-to-engage and time-to-disengage timers to further prevent flapping.
