We have created a page where our users can test the bandwidth they can benefit when upgrading the firmware on their controllers. To have a valid result, the test has to be made while in the same network with the controller.
Right now, we have download servers in multiple parts of the world. Thanks to geolocation, every client will connect to the nearest endpoint when downloading.
To test, one can use https://spd.mios.com and choose any of the servers there. We save some telemetry data, like IP address, location, download and upload speeds, browser.
This test does not get you to the closest server automatically.
