Hello Tor,

The OONI team published a report on network disruptions in Sierra Leone and established a new partnership with a local human rights organization in South Sudan. We also updated more test lists based on research, and we continued to make progress on probe orchestration, the development of the Windows app, and on the revamping of our mobile apps. We experimented with creating and publishing our first short documentary, and we continued to collaborate with community members on tracking censorship events worldwide.

# Established new partnership

We are excited to have formally established a new partnership with South Sudan's The Advocates for Human Rights and Democracy (TAHURID).

As part of our new partnership, we aim to collaborate on the study of internet censorship in South Sudan through the collection and analysis of OONI Probe network measurements.

# Updated test lists

We carried out research (https://ooni.torproject.org/get-involved/contribute-test-lists/#test-list-re...) https://ooni.torproject.org/get-involved/contribute-test-lists/#test-list-research%29 to identify more URLs to test for censorship in Zimbabwe and Venezuela. Based on this research, we updated the following test lists:      * Zimbabwe: https://github.com/citizenlab/test-lists/pull/327

* Venezuela: https://github.com/citizenlab/test-lists/pull/329

Overall, based on research, we have updated the following 5 test lists over the last months:

* Zimbabwe: https://github.com/citizenlab/test-lists/pull/327

* Venezuela: https://github.com/citizenlab/test-lists/pull/329

* Sierra Leone: https://github.com/citizenlab/test-lists/pull/320

* Egypt: https://github.com/citizenlab/test-lists/pull/336      * Mali: https://github.com/citizenlab/test-lists/pull/304

During April 2018, we also updated the following test lists based on URLs provided by community members:

* Kazakhstan: https://github.com/citizenlab/test-lists/pull/330

* Ethiopia: https://github.com/citizenlab/test-lists/pull/326

* Venezuela: https://github.com/citizenlab/test-lists/pull/333

* Uganda: https://github.com/citizenlab/test-lists/pull/334

# Report on network disruptions in Sierra Leone

We collaborated with Sierra Leone's Campaign for Human Rights and Development International (CHRDI) to monitor censorship events during the country's election period.

OONI data collected and analyzed from Sierra Leone did not show any significant signs of internet censorship. Even though WhatsApp and Facebook Messenger were accessible, their testing presented high execution time, indicating some form of performance degradation on the network.

Amid Sierra Leone's runoff elections, two network disruptions occurred. We examined these disruptions via Google traffic and BGP data, and published a report: https://ooni.torproject.org/post/sierra-leone-network-disruptions-2018-elect...

# Progress on Probe Orchestration

We made a lot of progress on implementing probe orchestration for automatically running network measurements on mobile OONI Probe. See: https://github.com/ooni/orchestra

Some highlights include:

* Integrating the experiment signing with the Yubikey 4 hardware security module * Significant refactoring of the codebase to make it easier to separate the alert push notification logic from that of experiment notification * Renaming of Proteus to OONI Orchestra * Upgrading the web frontend to the latest dependency versions

The unmerged branch containing the above changes is the following: https://github.com/ooni/orchestra/pull/44

# Progress on the Windows app development

In collaboration with Simone Basso, we iterated on integrating Measurement Kit into the Windows OONI Probe desktop app (https://github.com/measurement-kit/go-measurement-kit/tree/feature/windows+b... https://github.com/measurement-kit/go-measurement-kit/tree/feature/windows+binaries%29) https://github.com/measurement-kit/go-measurement-kit/tree/feature/windows+binaries%29.

# Revamping the OONI Probe mobile apps

As part of our work on revmaping the OONI Probe mobile apps, we continued to make progress on the design and UI, and we released a new testflight for iOS which includes new copy and all of the strings.

We also created a design brief for new illustrations to be included in the revamped mobile apps, and we started working with illustrators.

# Short documentary on internet censorship in Cuba

We published a short documentary that we created during our trip to Cuba last year, titled: "ParkNet: Exploring Internet Censorship in Cuba".

This 5-minute film features some of our key findings on our study of internet censorship in Cuba and is available here: https://ooni.torproject.org/post/parknet-short-documentary-cuba/

More in-depth findings are available via our research report (https://ooni.torproject.org/post/cuba-internet-censorship-2017/) https://ooni.torproject.org/post/cuba-internet-censorship-2017/%29.

This short documentary is our first experiment in presenting censorship findings with video.

We have set up an OONI YouTube channel where we plan to publish more videos in the next months: https://www.youtube.com/channel/UCQhDgj9wBf4_w5bWFvLlq-w

# Community use of OONI data

## Blocking of IM apps in Chad

OONI data was referenced in Internet Sans Frontieres' press statement regarding the blocking of WhatsApp, Facebook Messenger, Viber and BCC in Chad: https://internetwithoutborders.org/chad-is-blocking-social-media-and-messagi...

## Blocking of news outlet in Venezuela

OONI data confirmed the blocking of news outlet El Pitazo in Venezuela. We provided an analysis and interpretation of measurements that supported IPYS Venezuela's report on the blocking: https://ipysvenezuela.org/alerta/dos-medidas-de-censura-han-afectado-a-el-pi...

## Citizen Lab Netsweeper report

OONI data was used to identify blocked websites and middleboxes in the Citizen Lab's research report, "Planet Netsweeper": https://citizenlab.ca/2018/04/planet-netsweeper/

# Community activities

## OONI presentation at the International Journalism Festival (IJF)

On 13th April 2018, OONI was presented at the International Journalism Festival (IJF) in Italy on a panel that discussed the many faces of censorship. More information about this panel is available here: https://www.journalismfestival.com/programme/2018/states-companies-algorithm...

## Blog post on recent participation at conferences

We published a blog post on our recent participation at conferences in Africa, India, and Europe. Our blog post is available here: https://ooni.torproject.org/post/ooni-in-africa-india-europe-conferences/

## Community meeting

We hosted our monthly community meeting on 24th April 2018. As part of the meeting, we discussed the following:      1. Recap of what OONI has been up to over the last month

2. Outreach: How to communicate OONI Probe more effectively and engage wider audiences

3. Community engagement challenges: Monitoring censorship events in Chad and elsewhere in Africa

# Userbase
