The LU-Alert challenge: alerting without causing panic

The piercing ringtone blaring from a phone vibrating with all its might, several times a day, is a glimpse of a country at war that tourists, particularly Luxembourgers, experienced despite themselves when they had the misfortune to spend a few days in Dubai at the end of February, as Iran retaliated against American and Israeli missiles by attacking US bases in its neighbouring countries.

This deafening alert warns of imminent danger and is one of the most common ways of warning people of a serious threat, whatever its nature. It has sounded only once in the Grand Duchy – and even then, by mistake – and for good reason: the LU-Alert system and its range of channels for alerting the population only date back to autumn 2024. It succeeded the short-lived GouvAlert, the application created in 2018 following the flash floods that hit the country on 1 June. "It was an initial digital project with the idea of having an app available to the government to alert the population as quickly as possible, " recalls Alain Becker, Director General of Civil Security at the Ministry of Home Affairs. "The application was based on less-developed technology, but the idea was already to group together as many administrations and entities as possible that had to alert the population, bearing in mind that each administration had its own system and its own application, some of which still exist."
