Dutch Government Turns to NixOS After US Sanctions Cut ICC's Microsoft Access
After U.S. sanctions cost the International Criminal Court's chief prosecutor his Microsoft email access, the Netherlands launched a program to move government IT off American software and onto the open-source NixOS.

When the United States sanctioned the International Criminal Court in The Hague, the fallout went beyond diplomacy. The ICC's chief prosecutor lost access to Microsoft services, including email, effectively cutting off a core piece of the court's daily operations. For the Dutch government, the episode was a wake-up call: reliance on foreign-controlled software meant that critical government functions could be switched off at another country's discretion.
In response, the Netherlands launched DAWO, or Digitaal Autonome Werkomgeving Overheid — the Digital Autonomous Work Environment for Government. The initiative aims to overhaul the technology stack used across Dutch public institutions, from operating systems to office software and cloud services, so that no single foreign power can hold the government's digital infrastructure hostage again.
According to Dutch outlet Tweakers, as reported by It's FOSS, the new system is being built around NixOS, an open-source operating system known for its unusual approach to software management. Three service providers — SSC-ICT, DICTU and DUO-ICT — are handling implementation, with the Ministry of the Interior and Kingdom Relations overseeing the effort.
NixOS was chosen partly for technical reasons. It relies on the Nix package manager, which installs each software package in its own isolated directory with immutable, cryptographically signed contents. That design makes configurations easy to replicate across many machines — a significant advantage for an organization as large and varied as a national government. Reports suggest that as much as 90 percent of a given configuration can be reused across different deployments. NixOS also has the practical benefit of running on older hardware that would fail to meet Windows 11's system requirements.
The transition is still in its early stages. Eight Dutch municipalities are currently running trial deployments, and officials expect the first stable version of the platform to be ready by the end of 2027. Moving an entire government off entrenched, U.S.-built software is a lengthy and complex undertaking, but the Netherlands appears committed to seeing it through.
