A Paris court has ordered DNS4EU - an EU-funded, European-operated DNS resolver explicitly designed to protect digital sovereignty - to block access to dozens of pirate streaming domains, exposing a deepening tension between European infrastructure policy and member-state enforcement law. The rulings, issued on April 17 at the request of French broadcaster Canal+, add DNS4EU to a growing list of intermediaries caught inside France's accelerating site-blocking machinery.
How France's Blocking Reach Has Grown
France's approach to anti-piracy enforcement has shifted meaningfully since 2024. The Paris Judicial Court began by ordering residential internet service providers to block specific domains - a standard practice across several European jurisdictions. What changed was the court's willingness to look beyond ISPs and treat any intermediary capable of routing or resolving traffic as a potential enforcement point.
Cloudflare, Google, and Cisco's OpenDNS were among the first third-party DNS resolvers brought under blocking orders, establishing the legal principle that private infrastructure providers - even those not party to any infringement - could be compelled to act. VPN providers followed. Search engines were added. Each extension of the regime was premised on the same logic: alternative technical pathways allow determined users to circumvent blocks imposed on ISPs, so those pathways must themselves be closed.
The April 17 rulings represent a further evolution: rather than targeting intermediaries individually and sequentially, the court issued 18 separate orders on a single day, bundling ISPs, DNS providers, and VPN operators into a simultaneous enforcement action. This coordinated approach reduces the window in which users can pivot between unblocked alternatives. It is, structurally, a form of layered containment.
DNS4EU's Uncomfortable Position
DNS4EU occupies an unusual place in this dispute. Co-funded by the European Commission and operated by a consortium led by Czech cybersecurity company Whalebone, the service launched in June 2024 as a privacy-first, sovereign European alternative to U.S.-controlled resolvers. Its stated mission - ensuring "the digital sovereignty of the EU by providing a private, safe, and independent European DNS resolver" - sits awkwardly alongside a court order requiring it to suppress access to specific domains at the direction of a national judiciary.
The two rulings against DNS4EU are default judgments. Whalebone did not appear at the February 19 hearing and filed no defense, meaning the Paris court ruled entirely on Canal+'s framing. This is not an isolated pattern: Quad9, a Swiss-based non-profit DNS resolver with a similar privacy mandate, also defaulted in a parallel ruling issued the same day. By contrast, other named intermediaries - including major VPN providers and a large CDN provider referred to under a pseudonym in the published ruling - did contest the orders, raising arguments about technical feasibility, encryption constraints, and the applicability of the relevant French law. The court rejected those arguments, finding the objections insufficiently supported by concrete, quantifiable evidence.
DNS4EU has not explained its decision to forgo a defense. Neither the organization nor Whalebone responded to requests for comment. The silence is consequential: default judgments carry no public record of countervailing legal reasoning, which means the court's conclusions on scope, proportionality, and technical obligation face no documented challenge.
The Overblocking Problem
Independent testing of DNS4EU's public resolvers revealed that the blocking is not confined to French territory. Several of the targeted domains produced SSL errors and blocking notification pages for users located in other EU member states - users who are entirely outside the jurisdiction of the Paris court and who have no legal obligation placed on them by the French ruling.
This is textbook overblocking. The mechanism by which DNS4EU implemented compliance appears to apply uniformly across its infrastructure rather than filtering responses based on the originating user's geographic location. Whether that reflects a deliberate policy choice, a technical limitation, or an implementation error is unknown, because the organization has not responded.
The irony is precise. A service built and partially financed by the European Commission to give Europeans control over their own DNS infrastructure is now, under judicial compulsion from a single member state, restricting access for users in other member states who are not subject to that order. The European Commission has not publicly commented on this outcome.
What the Expansion of DNS Blocking Means
DNS blocking has always carried a structural tension at its core. The Domain Name System is a shared, universal resolution layer - it was not designed with enforcement geography in mind. Imposing nationally scoped restrictions through DNS resolvers requires either geolocation logic applied at the resolver level or blunter infrastructure-wide suppression. The latter is simpler to implement and easier to verify compliance with, but it produces exactly the kind of cross-border effect now visible in DNS4EU's behavior.
The broader legal architecture driving these orders - Article L. 333-10 of the French Sports Code, which permits blocking against "any person likely to contribute" to remedying infringement - is written in expansive terms. French courts have consistently interpreted that expansiveness broadly. Appeals against earlier rulings by major DNS and CDN providers were dismissed, and requests to refer questions about the law's EU compatibility to the Court of Justice of the European Union have been declined.
That makes the legal landscape increasingly settled in France's favor, at least domestically. For DNS resolvers operating across the EU, however, the practical question is no longer whether they can be ordered to block - they can - but how they manage the compliance burden, the cross-border spillover, and the reputational friction of being instrumentalized as enforcement agents by a court in a single member state. For a project whose entire value proposition rests on European digital independence, these are not minor complications.
