Ethiopia: Ongoing blocking of social media

On 9th February 2023, amid church split tensions and calls for anti-government protests, access to social media platforms (TikTok, Facebook, Telegram) was reportedly blocked in Ethiopia. Access Now also published a statement urging authorities in Ethiopia to stop blocking access to social media.

OONI data collected from Ethiopia provides signals of these blocks. Specifically, OONI data shows the ongoing blocking of Facebook and Telegram (since 9th February 2023) and YouTube (since 10th February 2023).

Blocking of Facebook

OONI data from the testing of Facebook in Ethiopia provides signals of blocking, starting from 9th February 2023.

The following chart aggregates OONI measurement coverage from the testing of www.facebook.com in Ethiopia between 11th January 2023 to 14th February 2023.

While the measurement coverage is rather limited, it’s worth noting that we start to observe a spike in anomalies (resulting in connection timeouts) from 9th February 2023 onwards, which coincides with the timing of the reported block. When inspecting the raw data of anomalous measurements, we observe that connections time out after sending the first TLS handshake message (ClientHello).

The TLS handshake timeouts observed in anomalous measurements suggest that access to Facebook is blocked by means of TLS-level interference. The latest measurements from the testing of Facebook continue to show that TLS handshakes result in timeout errors, suggesting that the block is ongoing.

Blocking of TikTok?

On 10th February 2023, TikTok presented anomalies (signs of blocking) when tested in Ethiopia.

The following chart aggregates OONI measurement coverage from the testing of TikTok (www.tiktok.com) in Ethiopia between 11th January 2023 to 14th February 2023.

As is evident, TikTok has been tested very few times in Ethiopia over the last month, and the limited measurement coverage provides an important limitation to our findings. Yet, it’s worth noting that while TikTok was previously found accessible, we see that its testing only presented anomalies on 10th February 2023, which coincides with the timing of the reported block.

We also observe anomalies in the testing of TikTok endpoints in Ethiopia on 10th February 2023, as illustrated below.

While the presence and timing of anomalies (some resulting in connection timeouts and others in connection resets) suggests the potential blocking of TikTok, our confidence in confirming this block is limited by the limited measurement volume.

Blocking of Telegram

On 9th February 2023, the OONI Probe testing of Telegram in Ethiopia started presenting a larger volume of anomalies, suggesting blocking of the service.

The following chart aggregates OONI measurement coverage from the testing of Telegram in Ethiopia between 11th January 2023 to 14th February 2023.

Specifically, we observe that all measurements collected from 18:52 UTC on 9th February 2023 onwards present anomalies. Through the raw data of these anomalous measurements, we see that while TCP connections to tested Telegram endpoints were successful, HTTP POST requests timeout after sending the request, and that the testing of Telegram Web (web.telegram.org) resulted in timeout errors. Based on OONI’s Telegram testing methodology, this suggests that access to both Telegram’s mobile app and web interface was interfered with.

Meanwhile, the latest measurements from Ethiopia (collected on 14th February 2023), suggest that the blocking of Telegram is ongoing.

Blocking of YouTube

Starting from 17:28 UTC on 10th February 2023, OONI data collected from Ethiopia started presenting anomalies every time YouTube (www.youtube.com) was tested, providing a signal of blocking.

Similarly to the testing of Facebook (discussed previously), access to YouTube appears to be blocked by means of TLS-level interference as the connection times out after the first TLS ClientHello message is written.

The blocking of YouTube is further suggested by Google’s Transparency Report, which shows a significant drop in YouTube traffic from Ethiopia during the same period (starting from 10th February 2023).

The above chart suggests that access to YouTube is still disrupted in Ethiopia, and this is further corroborated by the latest OONI measurements.

Conclusion

Ethiopia has blocked access to social media platforms several times over the past years. Some of these events coincided with Ethiopia’s national high school exams (allegedly in an attempt to prevent students from cheating) and following a coup attempt in the Amhara region. The latest (and currently ongoing) social media blocks in Ethiopia appear to resemble a similar pattern of information controls implemented in moments of tension.

That said, access to social media platforms is commonly blocked during moments of political tension in many countries around the world. Many of these cases raise concerns related to human rights, particularly since freedom of expression and access to information is critical in politically-sensitive moments.
