Network Monitor: A Couple Of Major Yet Short-lived Disruptions

Based on publicly available data, March was a relatively stable month in terms of network disruptions. However, three incidents took place that affected internet connectivity for some users in Iran and are worth noting. 

A fire started in the Telecommunication Infrastructure Company

According to Hamid Fattahi, CEO of the Telecommunication Infrastructure Company (TIC) and Deputy to ICT Minister Eisa Zarepour, some electric issues led to internet disruptions across Tehran and Alborz provinces for a few hours on March 4. As Fattahi said in an interview with IRIB News Agency, a fire erupted in the UPS and power supply systems at one of TIC’s centers following a power outage.”

The Ukraine war impacted connectivity in Iran.

According to IODA data, on March 6, 2022 Iran experienced nationwide internet disruptions due to the loss of 400G of bandwidth through the Europe-Persia Express Gateway (EPEG). EPEG is a high capacity fiber optic cable system which provides additional connectivity between Europe and the Middle East. This fiber optic cable has up to 3.2Tbit/s capacity and with a total length of approximately 10,000 km, EPEG offers route diversity by starting in Frankfurt, Germany and passing through Eastern Europe (including Ukraine), Russia, Azerbaijan, Iran and the Persian Gulf to Barka, Sultanate of Oman. 

The disruption, which lasted a little more than 4 hours, can be attributed to a cut in connection with the EPEG cable that passes through Ukraine. Iran’s ICT Minister confirmed the disruption on his Instagram account and, according to the TIC website, this issue was resolved after he issued an order to find alternative routing.
