What are test servers?
In order to test your internet performance, the SamKnows Whiteboxes need something to test against. We maintain a whole fleet of "test servers" to fit precisely this purpose - these are the servers that the Whiteboxes run measurements to.
The test servers run special software designed specifically for measuring network performance when communicating with the Whiteboxes.
It's really important that the test servers are deployed close to your home (and your Whitebox!) because the further the test server is from you, the higher the latency and the more we have to cross third-party networks, which can distort the results. This is why we operate so many test servers all around the world - locality to you is super important!
