[ooni-talk] Ethiopia report on recent censorship events

[Maria Xynou]

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).
