absence

Yesterday we attend an unprecedented event in our country. From one moment to another and in a matter of five seconds, 60% of all energy vanisheddisappeared. The entire peninsula ran out of light. The reasons are unknown how it was unknown in certain points of Spain that the blackout had been general. The light fell, ergo the wifi. Telecommunications, mobile networks fell, and networks were saturated. Contact family and friends to know if they were fine was an odyssey, as was accessing to the media and social networks to inform themselves of the last hour. No one knew what was happening, its reach, the reasons or the state of the situation. In such a context, it is worth asking what happened to Es-alertthe emergency alert system. Who is-alert depends on. The Civil Protection alerts system was launched on February 22, 2023 and serves to send notices to all mobile phones within an affected area. It is integrated into the national alert network and, therefore, is managed by the Ministry of Interior through the National Center for Emergency Monitoring and Coordination (CENEM) of the General Directorate of Civil Protection. Notice example received through the ES-Alert system | Image: mobile xataka This system is known as “112 inverse” and is available in “any part of the Spanish territory with mobile telephony coverage, either 2G (GSM), 3G (UMTS), 4G (LTE) or 5G”, as They explained from Moncloa The day of its launch. Civil protection, meanwhile, exposes that “the ES-ALErt system is available to the Emergency Coordination Centers of the Autonomous Communities in the framework of the National Civil Protection System” and that these centers, together with the aforementioned CENEM, are the “responsible, within their area of ​​competence, to define and issue the alerts when the situation requires it.” In a nutshell, that competition falls to the Autonomous Communities. What situations is used? According to Moncloa, Es-Alert is designed for phenomena such as “floods, fires, adverse meteorological phenomena, volcanic or chemical accidents, among other emergencies.” The question is what happens to this system when there is no electricity, when telecommunications are falling and a very high percentage of the population has no coverage. A mobile will not receive the notice if it has no coverage or is in plane mode, although it will do so when you recover the signal The networks worked (a time). The mobile network remained active for a while thanks, in part, emergency generators. VodafoneMasorange and Telefónica They have confirmed that although the blackout had affected telecommunications services and the mobile network, part of the system had supply thanks to electric generators and batteries. Es -Elert depends on that infrastructure to work, the question is whether it would have been effective. Lights and shadows. While it is true that Es-Alert is practically agnostic to the device and the version of the operating system, its effectiveness depends on the fact that there is electricity and that the receiving phones have coverage. Assuming that the ES-Alert system was available (because as we already know, there was no electricity supply), the reality is that an important thickness of the population would not have received the warning at the time because it did not have coverage. They would have received it when recovering the signal in the event that the emergency remained active in the area, but there is no guarantees that, by then, the notice would have been useful.

Public entities and organizations, which They urged the user to save battery and limit the use of mobilethey made their official communications through social networks such as X. Access not only to this social network, but to the media that echoed this information, it was not always possible due to the lack of coverage and mobile data network. The always eternal radio. The best informed citizen yesterday was the one who had a ancient operational radio thanks to two AA batteries. The radio works independently that there is coverage, mobile network or wifi. Emergency equipment They do not communicate by Walkie-Talkies By custom, but because in a fire in which everything has fallen, the radio will continue to function. If the broadcaster and the receiving device work, there is communication, and that is what happened precisely yesterday. The radios continued to function and counting the last hour of the blackout, which shows that an invention of the late nineteenth century is still important in the middle of 2025.
