Data center naming convention is explained here: http://www.leaseweb.com/en/about-us/data-centers

These servers are iperf3 compatible from port 5201-5210.
Each port can only have 1 connection at the time, therefore if the port is busy please try another one or wait a bit and try again.

The results can vary depending on the current network load on the Speedtest servers, which means the amount of iperf3 tests running at the same time period and the amount of Speedtest file downloads.

Quick guide on how to do default tests:

  • Install iperf3 and run the following command:  

Example on how to do a iperf3 default test

$ iperf3 -c speedtest.ams1.nl.leaseweb.net -p 5201 -6
