Iran has seemingly come under cyber-attack. Indeed, so powerful was the impact of this alleged attack that the internet was disrupted across the country. The NetBlocks internet observatory, which maps internet freedom in real-time, confirmed that there was extensive Iranian telecommunications network disruption on the morning of February 8. In a NetBlocks tweet, the national internet connectivity drop to 75% was said to be due to Iranian authorities activating the “Digital Fortress” cyber-defense mechanism, also known as DZHAFA.
