OONI measurements indicate censorship remains

In its most recent measurement report, the Open Observatory of Network Interference [OONI] concludes that “while social media censorship in Azerbaijan appears to have been lifted, the media censorship remains.” These and other findings are based on the recent measurement report produced in partnership with OONI. 

Here are some highlights.

Blocked websites

The news websites that presented signs of blocking in Azerbaijan (between December 2020 to February 2021) include:

🛑 azerbaycansaati.tv – at the time of blocking azerbaycansaati.tv in 2017, the Government of Azerbaijan claimed “a number of articles published” by the news website “included calls aimed at ‘forcible change of the constitutional order,’ ‘organization of mass riots,’ and other illegal activities.” 

🛑 www.24saat.org – a more detailed report about how 24saat.org was blocked can be found in this report, published by Qurium in 2017. 

🛑 www.abzas.net – DDoS attacks against abzas.net commenced on January 12, 2017, and lasted for eight days. During five full consecutive days, the website remained inaccessible until it was finally migrated to VirtualRoad.org’s secure hosting infrastructure.

🛑 www.azadliq.info – as a hosting provider for azadliq.info Qurium published this report about initial signs of blocking against this online news platform. The website was attacked numerous times according to documentation and forensic reports by Qurium. The technology deployed in these DDoS attacks was Allot and Sandvine DPI gear.

🛑 www.azadliq.org – the news website which represents the Azerbaijan Service for Radio Free Europe, was blocked on March 27, 2017. 

🛑 www.gununsesi.org – signs of DPI technology used in blocking gununsesi.org were once again documented by Qurium.

🛑 www.kanal13.tv – was among blocked websites in 2017 while its editor prosecuted [charges were dropped three years later.] 

🛑 www.meydan.tv – was also among the websites that were blocked in 2017 together with azerbaycansaati, azadliq.info and others. 

🛑 www.occrp.org – in response to the leaks about Azerbaijan Laundromat published by the Organized Crime and Corruption Research Project [OCCRP], the government of Azerbaijan suspended access to OCCRP’s website.

There is no official data on the number of blocked websites in Azerbaijan. The Ministry of Communication, High Technologies and Transportation has so far failed to provide accurate lists. This in itself is a violation of Article 13.3.6 of the Law on Information, Informatisation and Access to Information, which requests the Ministry to prepare a list of blocked websites if it has blocked access to a resource and the court upheld this decision.

In July 2018, the Prosecutor General’s Office launched criminal investigations against four news websites: criminal.az, bastainfo.com, topxeber.az and fia.az. The former two were accused of “knowingly spreading false information,” while the latter two were accused of “spreading unfounded, sensational claims in order to confuse the public.” Criminal.az is an independent website, known for its coverage of crime-related news, while bastainfo.com is affiliated with the opposition party Musavat. The latter two are run-of-the-mill online news websites.

In addition to the usual suspects, video streaming service Vimeo appeared to be briefly blocked during the testing coverage:

Circumvention

Several circumvention tool websites appear to have been interfered with in Azerbaijan during the testing period, as illustrated below:

The good news are that access to social media sites and apps was restored during the testing period. The following chart shows that while WhatsApp and Telegram were blocked in November 2020, both apps (along with Facebook Messenger) have been accessible in recent months:

Azerbaijan September – November 2020 OONI Measurement Results

On September 27, the government in Azerbaijan introduced a series of restrictions on Internet access as a result of military operations in Nagorno Karabakh. Users in Azerbaijan were left with limited Internet access while access to a number of social media platforms, as well as communication apps, were restricted. 

Azerbaijan Internet Watch, and OONI collected data based on OONI measurements from Azerbaijan. Below is the report looking at data between September 2020 to November 2020. 

According to collected OONI data, Azerbaijan experienced the blocking of independent media websites as well as signs of potential circumvention tool site blocking. However, further OONI Prote testing is required to confirm these censorship events. Azerbaijan Internet Watch continues to monitor the situation. 

Starting on September 27, a number of social media services indicated signs of blocking in Azerbaijan. Among these were:

Whatsapp: between 27th September 2020 to 11th November 2020 , all OONI Probe WhatsApp tests showed signs of WhatsApp blocking. This is illustrated through OONI Probe WhatsApp measurements collected from multiple local networks in Azerbaijan. Previously according to the same measurements, no such instances were documented. The measurements indicated that attempted connections to WhatsApp’s registration service and web interface (web.whatsapp.com) failed. In some cases HTTP request to web.whatsapp.com succeeded while HTTPS request failed as illustrated below. 

This could be an indication of SNI based filtering of WhatsApp. We also observe that the tls_handshakes field presented failures, further suggesting that access to WhatsApp was blocked in Azerbaijan by means of SNI based filtering.

This pattern was seen across multiple ISPs in Azerbaijan between 27th September 2020 to 11th November 2020.

Telegram: Similarly to the testing of WhatsApp, OONI measurements presented signs of Telegram blocking in Azerbaijan between 27th September 2020 to 11th November 2020. But unlike WhatsApp, a few Telegram tests during this period were successful. This is illustrated through OONI Probe Telegram measurements collected from multiple local networks in Azerbaijan between 1st September 2020 to 27th November 2020. The following table illustrates OONI measurements collected from the testing of Telegram and WhatsApp on 5 different networks in Azerbaijan between September 2020 to November 2020.

We not only observed similarities between the date range of potential blocking (of WhatsApp and Telegram), but we also saw potentially similar censorship techniques, as the HTTP requests to Telegram Web (web.telegram.org) timed out as well. Similarly to WhatsApp, we observed a timeout in the TLS handshake, suggesting TLS level interference of Telegram as well. As a result, it is possible that internet users in Azerbaijan couldn’t use the Telegram and WhatsApp mobile apps (on the tested networks) during this time period (between 27th September 2020 to 11th November 2020), even though connections to the tested app endpoints succeeded.

Social media sites: apart from WhatsApp and Telegram, several social media websites presented signs of blocking as well, starting from early October 2020. These include:

It is however, important to note these sites’ limited testing coverage limits Azerbaijan Internet Watch and OONI’s confidence with respect to their blocking, and they have not been tested more recently especially after the conflict ended.

AIW and OONI continue monitoring the situation with blocking.
