News

June 7, 2010: The ExoneraTor now uses the most recent network information as its data basis (as opposed to monthly snapshots). As a by-product, network status consensuses and server descriptors are now browsable by valid-after time and descriptor digest, respectively. More sophisticated descriptor search functions will follow.
June 7, 2010: The graphs on user-experienced download times are now drawn using (a modified) ggplot2. Modifications to ggplot2 include drawing a ribbon only for intervals with non-NA values and positioning the legend at the top of a graph. This concludes the transition to ggplot2 and will greatly facilitate dynamic graph generation in the future.
May 26, 2010: The monthly relay and bridge descriptor tarballs are now updated every day. Beginning with May 2010, the bridge descriptor tarballs do not contain country codes anymore, because it was tough to maintain. If your research requires this or any other detail, contact us and we'll sort something out.
May 25, 2010: The graphs on daily bridge users are now more accurate by excluding broken "geoip-stats" data of 0.2.2.x versions and including "bridge-stats" data of bridges running 0.2.2.7-alpha or higher.
May 19, 2010: The graphs on recurring users and bridge users are now accompanied by CSV files containing peak and average daily users per month by country.
