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 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.

Pointed snowflake-broker.torproject.net (one of three domain names for the Snowflake broker) to a new broker instance set up with IPv6. Metrics unintentionally start being collected from the new instance, instead of the old instance that was still in use.
