Open Observatory of Network Interference (OONI) Foundation

I'm excited to (finally!) speak in my home city of Athens and meet the FOSS community in Greece! 😍 Tomorrow at FOSSCOMM 2026, I'll be talking about why free software matters more than ever for human rights. ✊ I'll also be hosting an OONI booth on both days of the conference, so come say hi, grab some OONI stickers and brochures, and learn how to use OONI tools! 🐙 ✨

Congrats to Deutsche Welle for launching the Internet Censorship Monitor! 👏 We're happy that OONI data helps support this effort. 🙏🐙♥️ This builds on our collaboration with Deutsche Welle on the News Media Scan app: https://lnkd.in/dGGRtS-k https://lnkd.in/e2hPg-_N

How accessible is dw.com across the DW target regions? 🌐 The Internet Censorship Monitor provides an interactive overview of where dw.com is freely available and where access is blocked. 👉 Explore the map and see the situation country by country: https://lnkd.in/eKx4NUuM Access to independent information should not stop at digital borders. That's why DW works to make its journalism accessible to people around the world, including in regions affected by internet censorship and access restrictions. Through censorship circumvention solutions such as the DW Access App (link in comments), users can continue to access independent information.

📊 Wir ergänzen unsere internen Daten kontinuierlich durch externe Messungen – etwa mit dem News Media Scan, den wir gemeinsam mit OONI betreiben. 🤝 Dank der Unterstützung zahlreicher Datenspender*innen weltweit können wir gemeinsam mit der Non-Profit-Organisation belastbare Aussagen über Zensur in den Zielregionen der DW treffen. Die anhaltenden Sperrungen von dw.com machen wir nun erstmals in einer öffentlich zugänglichen Karte sichtbar. 🔗 News Media Scan auf Google Play: https://lnkd.in/dGGRtS-k 🔗 News Media Scan im App Store: https://lnkd.in/e2hPg-_N

After finding the guy who carries half of the world’s internet traffic on his back, we decided to bring the person who carries the receipts of every government that tried to switch off the internet on her back. Maria Xynou is the Co-founder of the Open Observatory of Network Interference (OONI) Foundation and serves on the Board of Directors of The Tor Project. When a regime blocks an app or throttles the internet and claims it’s “just a temporary technical glitch,” her work is the reason the rest of the world has the receipts. Through OONI Probe, volunteers have collected over 2 billion network measurements across 242 countries and territories, building one of the world’s largest open datasets on internet censorship (which even got OONI Explorer blocked in Russia, basically the ultimate 5-star review for an anti-censorship tool). On October 31 and November 1, she’s joining us at the University of West Attica for FOSSCOMM 2026. Come hear how open-source software exposes global censorship in real time, find out whether your ISP is actually just having a bad day and raid the OONI booth for stickers, which no government has managed to ban yet. Registration is free and your ISP hasn’t blocked this link yet, so you officially have zero excuses to miss it: https://2026.fosscomm.gr

This week, we're excited to be at Collaboration on International ICT Policy for East and Southern Africa (CIPESA)'s Forum on Internet Freedom in Africa (FIFAfrica 2026), one of Africa's leading digital rights conferences! 😍 https://lnkd.in/gzt7Pfn8 Interested in measuring internet censorship? Come meet us at the Digital Reality Walk on September 30 & October 1 to learn how to use OONI tools! 🐙 #FIFAfrica26 #InternetFreedomAfrica

Are you attending Team CommUNITY's Global Gathering in Portugal this week? 😃 Join us for a session on "Strengthening Rapid Response Efforts to Censorship Events" 🐙✊️ 📌 When?

❗️ Today, OONI and Women on Web (WoW) co-published a new research report, documenting the blocking of Women on Web (WoW) and Women Help Women (WHW) reproductive health websites in Italy based on OONI data. Read our report here: https://lnkd.in/dUJvXXxw Learn about the impact of these blocks through the joint press release by WoW and WHW: https://lnkd.in/dwPTxXxQ Starting in mid-February 2026, at least 6 ISPs in Italy – including several of Italy’s largest networks by end-user population – started blocking access to the Women on Web (WoW) and Women Help Women (WHW) reproductive health websites through DNS tampering. OONI data shows multiple forms of DNS interference, including bogon IP responses, NXDOMAIN errors, and DNS responses directing users to block pages. According to the World Health Organization (WHO), access to accurate health information is a key component of enabling individuals to understand their healthcare options, make informed decisions, and safely navigate reproductive healthcare. 🙏 Restricting access to such information may therefore undermine people's ability to obtain timely and safe care and, ultimately, to effectively exercise their reproductive rights. We thank OONI Probe users in Italy for contributing measurements. 🙏🐙 #ooni #censorship #italy #reproductivehealth #opendata

From Heuristics to Anonymous Credentials: Assessing OONI's Approach to Bad Measurements https://lnkd.in/d2rGFGR6 In our latest blog post, we share: • New heuristics and strategies for mitigating faulty measurements • An evaluation of the effectiveness of our new Anonymous Credential System 🐙✨ Through the OONI Anonymous Credential System, we aim to cryptographically protect the OONI dataset from the (intentional or unintentional) submission of faulty measurements, and to strengthen trust in OONI data. #ooni #AnonymousCredentials #opendata #censorship #ooniprobe
