Hello,

Today OONI and Nigeria's Paradigm Initiative jointly published a research report examining information controls during Nigeria's 2019 elections.

We have published two versions of this report:

* Nigeria's 2019 elections through the lens of network measurements: https://ooni.io/post/2019-nigeria-internet-censorship/ (focusing on OONI analysis)

* Nigeria's 2019 elections through the lens of digital rights: https://paradigmhq.org/download/the-2019-nigerian-elections-through-the-lens... (includes full PDF with broader digital rights analysis)

Thousands of OONI measurements collected from 16 different ASNs between 1st February 2019 to 31st March 2019 suggest that major internet services were accessible in Nigeria throughout the 2019 general elections. Most of the tested websites were found to be accessible, while popular instant messaging platforms, WhatsApp and Facebook Messenger, were working as well.

However, a number of sites hosting content associated to the Biafra secessionist movement remained blocked.

Recent OONI measurements show that Globacom continues to block these sites by means of TCP/IP blocking, MTN by means of DNS tampering, and Airtel at the HTTP layer. This is strongly suggested by the fact that the same network anomalies (in comparison to last year) are observed on the same networks with regards to the testing of the same list of sites. Out of more than a thousand URLs tested in total, only sites associated to Biafra consistently presented network anomalies throughout the testing period.

You can expand upon this study through the use of OONI Probe (https://ooni.io/install/) and OONI data (https://ooni.io/data/), which is openly available.

Best,

Maria.
