An interesting situation occurred with the Iranian state TV channels in early March. Suddenly, several of them experienced no signal on their televisions overnight. According to reports, the incident happened at night local time, and the broadcast was simply interrupted. It is not yet clear exactly what caused this, but it seems to have been some kind of attack that affected the transmission infrastructure. The curious thing is that so far they haven't released many details about what actually happened or the true extent of the damage. Several channels simultaneously had no signal, which suggests it wasn't an isolated problem. We can only imagine what might have motivated such an attack and what the goal behind it was. Situations like this highlight how vulnerable media infrastructure can be to certain types of attacks. Anyway, it was an episode that drew attention, but with little transparency about the details. The fact is that the no-signal TV was quite noticeable to those who were watching.
