What is a Speed Test?

In reality, a speed test measures the latency between your computer and the location of the speed test file, not the capacity of the connection. Speed and capacity are closely related, thus a speed test does provide a general idea of your Internet capacity. GCI believes that all of our customers have access to the full capacity they have selected.
