The data is also archived together with the location of the client. This is determined based on the client IP address. Speedtest.net uses GeoIP databases from MaxMind to position the client and by default locate the closest server since the transfer speed depends on the TCP window and TCP is not usually optimized for increased RTT. While the information in MaxMind's GeoIP databases is very accurate, it is not perfect. More information on Ookla's speed test can be found here.
