Description of OONI Probe

Are websites and social media apps blocked? Is your network unusually slow? Run OONI Probe to find out!
With this app, you will examine the blocking of websites and instant messaging apps, measure your network's speed and performance, and check whether systems that could be responsible for censorship and surveillance are in your network.
OONI Probe is developed by the Open Observatory of Network Interference (OONI), a free software project (under The Tor Project) that aims to uncover internet censorship around the world.
Since 2012, OONI’s global community has collected millions of network measurements from more than 200 countries, shedding light on multiple cases of network interference.
Collect evidence of internet censorship
You can check whether and how websites and instant messaging apps are blocked. The network measurement data you will collect may serve as evidence of internet censorship.
Detect systems responsible for censorship and surveillance
OONI Probe tests are also designed to uncover the presence of systems (middleboxes) that could be responsible for censorship and surveillance.
Measure the speed and performance of your network
You can measure the speed and performance of your network by running OONI's implementation of the Network Diagnostic Test (NDT). You can also measure video streaming performance with the Dynamic Adaptive Streaming over HTTP (DASH) test.
Open data
OONI publishes network measurement data because open data allows third parties to verify OONI findings, conduct independent studies, and answer other research questions. Openly publishing OONI data also helps increase transparency of internet censorship around the world. You can explore and download OONI data here: https://ooni.io/data/
Free software
All OONI Probe tests (including our NDT and DASH implementations), are based on free and open source software. You can find OONI software projects on GitHub: https://github.com/ooni. Curious to learn how OONI Probe tests work? Learn more: https://ooni.io/nettest/

  Error on ALL tests performed. EVERY time. No matter the test. BS!

  A great way to analyze a network, with lots of results. I've used it to compare different broadband providers, and have found it immeasurably useful as it doesn't just check speed, but also censorship levels and lots more.

  Very useful tool to run periodically. Easy to understand user interface.

  Version 2.6.0 is considerably slower to perform the website tests than previous versions. It took more than six hours to run the tests for 22 categories!

  That is the very useful application but I do not know " the middle box " is missing! Someone can guide me why is like that? Why is the middle box is missing?

  If I won't know the exact sites accessed, how would I prove why & how I accessed "evil" if I were confronted Guvmt? Also, considering the iron grip of the ISP lobby on "our" (ha ha) Lawmakers, and all agencies of guvmints of every country gone rogue anyway, what does this app accomplishe. All is lost, already. But I do favor the work done by the devs.
