A map of the number of servers / country is seen in the middle left below. The most servers/country were US (54), Australia (7), Russia(6), Brazil, Canada, Romania (5). The locations of the servers are seen in the map to the left. A summary of this data is provided to the client user in real-time showing average download speed, upload speed, and ping Round Trip Time (RTT).Īt the time of the data, Ookla had 193 servers in 68 countries. They calculate the throughput by knowing the amount of data transferred and then dividing this by the time taken to transfer the data in each direction. A chosen server (by default selected as the nearest server to the client, though the client/user can select their own server) downloads a file of incompressible data to the user's client and then uploads it. Ookla maintains a fleet of speed-testing servers all over the world. Mike Apgar and Doug Suttles of Ookla were kind enough to reply, answer questions, and on Decemprovide data suitable for importing into Excel (CSV format) and analyzing. Ookla solicited input so we contacted them by email on Novemto see if we could get more complete data from their archives. We could find publicly accessible archives of results from only ZDNet.AU which we have analyzed elsewhere. A Beltronica lists about 80 countries four of which are in Africa. NDT, NPAD, CNet and Speakeasy have servers in the US only, ZDNet.AU servers in Australia only, though it does not say we suspect ZDNet.UK probably has servers in the UK only.

Of these NDT and NPAD are mainly diagnostic tools. There are several active end-to-end throughput measurement web sites available today including Cnet, ZDNet.UK, ZDnet.AU, Ookla, NDT servers, NPAD servers, A Beltronica Telecom, Speakeasy. Part of this is to compare the results from direct measurements of throughput with those obtained from the PingER derived throughputs.

We are interested in alternative ways of actively measuring the throughputs for countries of the world especially for developing countries.
