Hello,

Today we published a report on the blocking of social media in Burundi amid its 2020 general election.

You can read the report here: https://ooni.org/post/2020-burundi-blocks-social-media-amid-election/

OONI measurements collected from Burundi reveal the blocking of 18 social media platforms on 20th May 2020 (election day), including skype.com, youtube.com, whatsapp.com, twitter.com, facebook.com, instagram.com -- among many others.

These sites appear to be blocked -- on Econet (AS37336) and Viettel Burundi (AS327799) -- through the use of some form of Deep Packet Inspection (DPI) technology, as the blocking only occurs when we attempt to establish an HTTPS connection (resulting in connection reset errors), as opposed to the IPs being blocked or the DNS queries being interfered with.

OONI data also shows the blocking of the WhatsApp and Telegram apps, and suggests that access to Facebook Messenger was blocked too.

Interestingly, the blocking of Facebook Messenger on the Lacell Burundi (AS327720) network was implemented on a DNS level by returning an IP address in the DNS answer which is in the “reserved for future use” 240.0.0.0/8 netblock.

As OONI measurements have been collected from multiple local networks in Burundi since 2016, we were able to compare measurements over time.

This is the first time that we are observing the blocking of social media in Burundi, and the blocking clearly appears to have started in the morning of 20th May 2020, on election day.

You can expand upon this study through the use of OONI Probe (https://ooni.org/install/) and OONI data (https://ooni.org/data/).
