About our CenturyLink internet speed test
The CenturyLink internet speed measures three things:
Download speed: The speed at which your device pulls data from the internet. Usually measured in Mbps or Gbps.
Upload speed: The speed at which your device sends data to the internet. Usually measured in Mbps or Gbps.
Latency (Ping): The time (measured in milliseconds) it takes for a signal to travel from your device to an internet server and back. Lower latency means your connection has a better response time for activities like gaming and livestreams.
How does the CenturyLink internet speed test work?
Our CenturyLink speed test works by sending a signal to a nearby test server and measuring how long it takes for the server to respond. The test also opens multiple simultaneous connections to the server to download and upload small pieces of data. Through that process, the test is able to determine how long it takes to collect and deliver the data and the amount of network bandwidth used in the process.
