The Netherlands Built a Nix-Basd Linux Desktop Because Microsoft Cut Off the ICC

U.S. sanctions that cut off the International Criminal Court prosecutor from Microsoft services and froze accounts prompted the Netherlands to build a sovereign desktop stack called DAWO (Digitaal Autonome Werkomgeving Overheid). DAWO is a government mandate to create a standardized, independent digital work environment covering the operating system, office suite, collaboration tools, cloud services, IT management and AI. The Interdepartmental Commission for Government Business Operations tasked SSC-ICT, DICTU and DUO-ICT with execution, while a BZK-associated team led development. Eight municipalities are already piloting the environment via the Association of Dutch Municipalities, and a first stable release is planned for next year after feedback from pilots and stakeholders.

NixOS was chosen as the foundation because Nix’s functional package-management model produces immutable, signed packages and fully reproducible system configurations, allowing broad reuse of setups across agencies - Rutger Putter estimates 80-90% configuration carryover between deployments - and it can run on decommissioned hardware that Windows 11 cannot. All code is hosted on domestic Forgejo/Codeberg instances to avoid reliance on GitHub/GitLab. openSUSE and Fedora were rejected due to commercial ties to SUSE and Red Hat/IBM. The move follows similar European shifts away from Microsoft in regions like Schleswig-Holstein, Denmark and France, where license savings have been redirected to support open source.
