BitTorrent Logs

Statistics pages from two large trackers, late 2003 to early 2004. The pages are HTML output from a PHP script, so you will need to parse them yourself to extract useful information. The data is sufficiently anonymized; the tracker did not provide IP address information about connected hosts nor did it provide information about the content of running torrents. Clients are identified using a session-unique 40-character ID, and torrents are uniquely identified using a similar key.
