We estimate the number of users by analyzing the requests induced by clients to relays and bridges.
This graph shows the estimated number of clients connecting via bridges. These numbers are derived from directory requests counted on bridges. Bridges distinguish connecting clients by IP version, so that graphs are available for both IP versions 4 and 6. For further details see these questions and answers about user statistics.
The following events have been manually collected on this wiki page and might be related to the displayed graph.
