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, and they distinguish connecting clients by transport protocol, which may include pluggable transports. Even though bridges don't report a combination of clients by country and transport, it's possible to derive and graph lower and upper bounds from existing usage statistics. 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.
