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 transport protocol, which may include pluggable transports, so that graphs are available for different transports. For further details check the documentation on Reproducible Metrics.
The following events have been manually collected in the metrics-timeline Git repository and might be related to the displayed graph.
