Hello,

Today, Gurshabad Grover (OTF Information Controls Research Fellow at OONI) and Simone Basso (OONI engineer) published a new post titled: "*How we're improving OONI data quality: An analysis of failed measurements*".

You may have noticed that some OONI measurements are annotated as "failed". This happens when the OONI Probe experiment fails to perform as expected (e.g due to bugs).

To better understand why some OONI measurements fail, Gurshabad and Simone analyzed 100 of the most failed Web Connectivity measurements collected (during 3 days in June 2022) from *India, Indonesia, and Pakistan* (300 measurements in total).

They found that Web Connectivity measurements failed to the following reasons:

* Instance of internet censorship

* Tested website was down

* Tested website was misconfigured

* Bugs

Out of the 3 countries, they found that *most failed measurements (more than 75%) from Pakistan and Indonesia were symptomatic of internet censorship*.

Based on this study, the authors identified some next steps for improving OONI data quality: https://ooni.org/post/improving-data-quality-analysis-of-failed-measurements...

We encourage researchers to analyze failed OONI measurements and help us further improve OONI data quality.

Thanks,

OONI team.
