Abstract
Concepts and technologies disclosed herein are directed to using proof of work for preventing distributed denial of server (“DDoS”) attacks. A server system can receive a resource request from a client system. The resource request can specify a resource. The server system can determine a congestion level based upon a load metric and a threshold. In response to determining that the load metric is above the threshold, the server system can determine that the congestion level is indicative of a high demand period. In response to the resource request being received during the high demand period, the server system can provide a work assignment to the client system. The server system can receive work results for the work assignment sent to the client system. In response to receiving the work results, the server system can process the resource request and can send the resource to the client system.
