Ethiopia report on recent censorship events
by Maria Xynou 21 Jun '19

21 Jun '19

Hello, We published a research report which shares network measurement data on the recent censorship events in Ethiopia: https://ooni.io/post/ethiopia-whatsapp-telegram/ OONI measurements collected from Ethiopia show the blocking of WhatsApp and Telegram between 15th to 18th June 2019. Both WhatsApp’s registration service (v.whatsapp.net) and web interface (web.whatsapp.com) were blocked by means of SNI filtering, but the blocks were lifted by 10:10 UTC on 17th June 2019. Many Telegram endpoints were blocked between 15th to 18th June 2019, strongly suggesting that Telegram’s mobile app was blocked (though connections to some Telegram endpoints were successful). The IP blocking of Telegram’s mobile app appears to have resulted in the (likely unintentional) blocking of web.telegram.org as well. We also share IODA and Google traffic data on the internet blackouts that appear to have occurred between 11th to 14th June 2019 (corroborating NetBlocks' relevant report). ~ OONI team. -- Maria Xynou Research & Partnerships Director Open Observatory of Network Interference (OONI) https://ooni.torproject.org/ PGP Key Fingerprint: 2DC8 AFB6 CA11 B552 1081 FBDE 2131 B3BE 70CA 417E

Jordan report: Facebook live-streaming interference during protests earlier this year
by Maria Xynou 14 Jun '19

Hello, Two days ago JOSA (Jordan Open Source Association) and OONI co-published a research report which examines Facebook live-streaming interference during protests in Jordan (between December 2018 to January 2019). The research report is available here: https://ooni.io/post/jordan-measuring-facebook-interference/ We also published a PDF version (thanks to JOSA!): https://ooni.io/documents/jordan-facebook-interference.pdf During protests in Jordan, locals reported that they were unable to view live-streaming from Facebook. But they also reported that viewing live-streaming was otherwise possible when protests were not taking place. Therefore, our first hypothesis was that perhaps people in Jordan couldn’t load videos on Facebook because they were using overloaded networks (rather than Facebook live streaming being interfered with). To examine this hypothesis and investigate further, we: * Enumerated Facebook cache servers to identify and map out those located in Jordan. * Tested the Facebook cache servers in Jordan, using OONI Probe. OONI measurements presented anomalies, providing signals of potential interference. * Ran a series of experiments using cURL. As part of such testing, we were able to rule out the hypothesis that Facebook users in Jordan couldn’t live-stream due to overloaded networks. Our findings suggest that Facebook Live Stream was temporarily interfered with in Jordan during protests between 20th December 2018 to 10th January 2019. In this report we share our findings in detail, as these methodologies could potentially be useful in examining similar cases elsewhere in the world. ~ OONI team. -- Maria Xynou Research & Partnerships Director Open Observatory of Network Interference (OONI) https://ooni.torproject.org/ PGP Key Fingerprint: 2DC8 AFB6 CA11 B552 1081 FBDE 2131 B3BE 70CA 417E
