On Wednesday 18 December 2025, Volt Luxembourg released an official statement in relation to the technical incident which impacted LuxTrust services on Tuesday 16 December, affecting government, financial, education and commercial services which utilise its authentication technology.
Volt said: “The total failure of the LuxTrust service for more than 24 hours from 16 to 17 December, followed by further ongoing disruptions, is an alarming warning sign. This incident is not merely a technical mishap but reveals serious structural weaknesses in Luxembourg's basic digital infrastructure. For Volt Luxembourg, it is clear that the current situation is unacceptable and requires immediate political action.”
They added: “LuxTrust bears enormous responsibility for key digital processes in our country – from government services to education and the financial sector. At the same time, it is a relatively small company. This discrepancy between responsibility and organisational resources is highly problematic. Critical national infrastructure must not depend on an undersized player that clearly reaches its limits in a crisis.”
The political party noted: “LuxTrust's de facto monopoly position in Luxembourg is particularly serious. There are no serious alternatives and, above all, no functioning backup or alternative systems. If LuxTrust fails, the country comes to a digital standstill. Such a ‘single point of failure’ structure contradicts all the basic principles of security, resilience and risk management, especially in a country that sees itself as digitally advanced and an international financial and administrative centre.”
On Tuesday 16 December LuxTrust experienced a disruption of service which began in the evening and continued into the following day, affecting authentication and a range of online services. Restoration operations began on Tuesday afternoon and continued overnight, resulting in a gradual return to service, including the restoration of LuxTrust authentication and electronic signature services by 12:40 on Wednesday 18 December.
LuxTrust confirmed on the evening of Wednesday 18 December that all of its services were “fully operational” as of 20:00 that day and announced a detailed review will be conducted and a follow-up communication will be issued accordingly.
