Network Monitor – June 2021

A a short post-election internet shutdown was implemented in the city of Yasuj, and a number of major internet providers suffered from internet outages.

 

Mobile Internet Cut Off in Yasuj

On June 20, mobile data was cut off for almost the entire day via Irancell and MCI in Yasuj, the provincial capital of Kohgiluyeh and Boyer-Ahmad Province. The localised shutdown was in response to a clash between two local tribes in relation to the results of local city council elections. The internet was partially restored on June 21 at around 16:00 local time, and by June 22 it had been fully restored.

According to local sources, the Tamoradi and Tirtaji tribes, which both had candidates standing in the city council election, clashed in the streets to protest the election results in support of their own candidate. As a result, police opened fire on protesters, wounding a number of people.

Just like we saw in the last localised mobile internet shutdown in Sistan and Baluchestan, no network measurement tools were able to identify this shutdown as it took place.

On July 3, ICT Minister Mohammad-Javad Azari Jahromi also confirmed in an interview with Digiato that local mobile data was disrupted in specific neighbourhoods in cities where Iranian university entrance exams (Konkour) was held. Azari Jahromi said: “It was requested that 3G and 4G internet not be active in the exam areas, which will definitely affect the neighborhoods where the exams were held.”
