Speed Test

An internet speed test measures the connection speed and quality of your connected device to the internet. It does so by running multiple consecutive tests that analyze different aspects of your internet connection, namely ping (latency), download speed, and upload speed. Each of these values represents the connection’s specific qualities, which you can read more about in the paragraph after the next. These should help you understand the final speed test results. But before we get to these, we first want to discuss how to perform each test.
