Research Servers.

Research servers are servers donated to SamKnows by research groups and commercial entities for use in collecting internet performance data. As part of the agreement when using research servers, data collected against these servers must be published and made publicly available.

Our research servers are primarily provided to us by Measurement Lab and Level 3 (now CenturyLink).


SamKnows has research servers available in 48 locations worldwide. Most of these locations have several research servers available, with a variety of upstream providers.
