Hello,

Today the OONI team is thrilled to announce the public launch of our *new Measurement Aggregation Toolkit (MAT)*!

Access the MAT here: https://explorer.ooni.org/chart/mat

Learn all about the MAT through our blog post: https://ooni.org/post/2022-ooni-mat/

*# What is the MAT?*

Imagine being able to track internet censorship based on real-time data collected from networks around the world.

And imagine being able to create your own charts (based on this data) with the click of a button.

That's the MAT! :)

The MAT is a tool that enables you to *create your own custom charts based on aggregate views of real-time OONI data* collected from around the world.

Use the MAT to* track internet censorship worldwide* based on OONI data!

*# Who is the MAT for? *

The MAT was built for researchers, journalists, and human rights defenders interested in examining internet censorship around the world.

*# Why use the MAT?*

When examining cases of internet censorship, it's important to *look at many measurements at once* ("in aggregate") in order to identify trends and patterns, and answer key questions like the following:

* Does the testing of a service (e.g. Facebook) present signs of blocking every time that it is tested in a country? This can be helpful for ruling out false positives. * What types of websites (e.g. human rights websites) are blocked in each country? * In which countries is a specific website (e.g. bbc.com) blocked? * How does the blocking of different apps (e.g. WhatsApp or Telegram) vary across countries? * How does the blocking of a service vary across ASNs? * How does the blocking of a service change over time?

When trying to answer questions like the above, we normally perform relevant data analysis (instead of inspecting measurements one by one).

The MAT incorporates our data analysis techniques, enabling you to answer such questions without any data analysis skills, and with the click of a button!

Further details on using the MAT and interpreting MAT charts are available through our blog post: https://ooni.org/post/2022-ooni-mat/

We hope the internet freedom community finds the MAT useful for investigating and responding to internet censorship events around the world.

If you have any questions, feedback, or feature requests, we’d love to hear from you! You can open a ticket (https://github.com/ooni/explorer/issues/) or write us an email (contact@openobservatory.org).

We thank all OONI Probe users worldwide who have contributed (and continue to contribute) measurements, supporting the MAT. We also thank community members for their invaluable feedback. <3

Thanks,
