Monitoring a network site to detect adverse network conditions

摘要

A network protection service is presented. The network protection service is configured to establish an arrangement with a subscribing host for providing assistance to the subscribing host upon detection of a triggering condition. A set of rules corresponding to the subscribing host for filtering network traffic directed to the subscribing host is determined. The network protection service monitors for a triggering condition for providing protective assistance for the subscribing host, and upon detection of a triggering condition, provides protective assistance to the subscribing host. The protective assistance includes causing network traffic directed to the subscribing host to be rerouted to the network protection service. The protective assistance further includes filtering the network traffic rerouted to the network protection service according to the set of rules corresponding to the subscribing host. At least some of the filtered network traffic is forwarded to the subscribing host.
