OONI: Tor bridge reachability

Summary

Total reports processed: 1158
Total tests processed: 37237
Latest report processed: 2017-06-07 22:12:09
Number of faulty tests filtered from results: 737
Number of countries with bridge reachability measurements: 17

Using reports generated by the OONI-probe measurement test suite, collected every hour from Tor's report repository, the following graph shows an overview of global tor bridge reachability.

This page contains two visual analysis tools:

Timelines of Tor transport types, both as a global aggregate and per country
A bridge measurements explorer, providing a means to navigate measurements from the OONI bridge_reachability reports.

OONI Tor bridge measurements explorer

The bridge explorer is a visualization meant to indicate reachability of Tor bridges. We use raw data available from the OONI reports section. This page shows the results of reports that were returned as "successful", "failed" or "null", aggregated by country and by bridge, shown chronologically.

Click on a 'day' or 'week' element in the calendar of a month to browse the OONI measurements related to its visual representation.

Goals and methodology

Goals

The current implementation of bridge report visualization from the OONI-probe generated reports does not attempt to make any analytic statement. This iteration is restricted to providing a way to visually navigate the available data.

Caveats

The OONI network testing suite has been under heavy development, a non trivial exercise to say the least. As a consequence the reporting format has improved over time and distribution probes to enable wide coverage understandably suffered. The corresponding graphic depiction of these reports are equally spotty. We are confident that caveat will become moot in the near future.
You can participate in increasing distribution of ooni-probes. Please first familiarize yourself with the project
There is a known bug which at this time makes 20% of the tests not suitable for this data visualization.

Assumptions

No assumptions currently made

Methodology

There is currently no intermediate analysis. The methodology is very straightforward, acquisition and presentation of the ooni-reports.
