Various embodiments enable a server system to transmit a test workload to N distributed devices, request that the N distributed devices execute the test workload by requesting a service from a network site, and receive results from the N distributed devices indicating a quality of service received by the N distributed devices. In one embodiment, a computer-implemented method may include: transmitting an incentive to M number of distributed devices to join a distributed processing system, transmitting a test workload to N number of distributed devices, the N distributed devices being a subset of the M distributed devices, sending a request to the N distributed devices to execute the test workload by accessing and requesting at least one service from at least one network site, and receiving results from at least some of the N distributed devices, the results indicating a quality of service provided by the at least one network site to at least some of the N distributed devices.
