The following application statistics are based on the analysis of web server requests. All data comes from Tor web server logs which are provided in a stripped-down version of Apache's "combined" log format without IP addresses, log times, HTTP parameters, referers, and user agent strings.
This graph shows absolute numbers of requests to Tor's web servers related to Tor Browser. Initial downloads and signature downloads are requests made by the user to download a Tor Browser executable or a corresponding signature file from the Tor website. Update pings and update requests are requests made by Tor Browser to check whether a newer version is available or to download a newer version.
