When you run the Uswitch internet speed test, our tool will measure your broadband speed by downloading and uploading tiny bits of data, which are then sent to our UK servers.
How long it takes for those bits of data to reach our servers gives us a measure of the overall time it takes for them to be sent and then received by your device. This, therefore, allows us to accurately assess the speed of your broadband connection, but only in that particular moment.
You can read more about how our internet speed test works in our technical specifications FAQ further down the page.
