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 resolve client IP addresses of incoming directory requests to country codes, so that graphs are available for most countries. For further details see these questions and answers about user statistics.
The following events have been manually collected in the metrics-timeline Git repository and might be related to the displayed graph.
