Reachability of Censorship Circumvention Tools

The charts below display aggregate views of OONI data based on the testing of the following circumvention tools:

Please note that the presence of anomalous measurements is not always indicative of blocking, as false positives can occur. Moreover, circumvention tools often have built-in circumvention techniques for evading censorship.

We therefore recommend referring to Tor Metrics and to the Psiphon Data Engine to view usage stats and gain a more comprehensive understanding of whether these tools work in each country.
