![]() ![]() Do note how "closest" is not measured geographically but rather by what our networks thinks is the closest location. Tele2 speedtest service utilizes this to send you to the closest location in our network. Sparse files, such as the ones provided here via HTTP and FTP, can be created with something along the lines of: dd if=/dev/zero of=my_large_file bs=1 count=0 seek=10GĪnycasting is a technique where a single IP address is used in multiple locations in a network and packets are sent to the closest server. TCP windows have been slightly tweaked to support higher throughput. A small script called cleandir is used to clean the upload directory of the FTP server to avoid filling the file system with temporary uploaded files. Debian Linux is the operating system used, nginx for serving web pages and sparse files via HTTP and vsftpd is used for FTP. Each location consists of a 1U Supermicro server with an octacore Xeon E3-1240 V2 running at 3.4GHz, 32GB of RAM and an Intel 10GE NIC (82579LM chip). ![]() See how your country is affected by this new view and see how well internet speeds are improving where you live and if everyone is seeing the same benefit.Įditor’s note: This article was updated on April 18 to note the extended deadline for discontinuing the “mean” tab.This page and the listed speedtest services are hosted on a number of servers spread through Europe (see locations). The Speedtest Global Index remains the best source for worldwide internet rankings. Countries whose rankings increase with the switch to median were likely held back by small numbers of low-performing tests.Īnd here are the countries that see the largest changes in rank, both positive and negative. The same is true with extremely low numbers. In the example we gave above, we saw how rare, but extremely large values can sway the mean. You can see how this affects the top 10 list in the graphic below. On fixed broadband, Algeria sees a dramatic increase of 30 places while Venezuela suffers the largest drop of 35 places. Countries like South Korea where 5G is well established and widely available see little change in their mobile rankings. ![]() Namibia jumps 23 places on mobile while Ireland drops 28 places on mobile. This changes the rankings, but not for everyoneĬhanging the Speedtest Global Index from mean to median shakes up the global rankings quite a bit. Switching the Speedtest Global Index to median allows countries where a greater share of people have high speed internet to rank higher on the Index, rather than rewarding countries where a few areas have really high speeds and everyone else is left waiting. This is worth celebrating, but mean values can mask the fact that not everyone’s internet is improving. You can see how that one final value of 99 draws the mean, the arithmetical average, way up whereas the median continues to reflect the typical value of the set.Īs 5G and gigabit internet have expanded across the globe, we are seeing more and more high speed results on Speedtest®. The chart below shows how median and mean return very different values when considering a simple number set of ten values. In statistical terms, median is less likely to be influenced by outliers than mean is. Median is a measure that captures the typical user’s experience. Speaking of which … We are making this change because median is a better measure of everyday experience This gives you time to adjust to the new metric and play with the comparisons between median and mean to gain a deeper understanding of why we are making this change. This toggle will be available at the top of the page for the next three months. The default view for this toggle shows median speeds as that will be the metric used on the Speedtest Global Index going forward. We have included a toggle at the top of the Speedtest Global Index so you can switch between median and mean speeds. Read on for details as to why we are making this switch and the impact we expect it to have on world rankings for fixed broadband and mobile internet speeds. While we initially planned to switch entirely to median on February 15, 2022, we have extended the date the “mean” tab will be available until Februto allow regulators who rely on this information to transition over to the new metric. Starting today, we are also including data on median performance to better reflect the speeds a user is more likely to achieve in a market and we will eventually transition to only displaying median speeds. The Speedtest Global Index ™ has long been the go-to resource for detailed information about internet performance around the world. ![]()
