Systems and methods for predicting throughput in a network are described herein. The systems and methods use, in some examples, impaired DNS lookup times to predict what a throughput measurement would have been at the time of the issue had a measurement been taken. Using impaired DNS lookup times rather than constantly measuring throughput can reduce the workload of the cellular network while also reducing the storage capacity needed to measure throughput values for all of the devices using the cellular network. Throughput prediction may be used in other ways, including, but not limited to, device testing and assessment.
