Cloudflare, the US-based web infrastructure and security giant, has taken a bold stance against global site-blocking measures, urging the Office of the United States Trade Representative (USTR) to treat these practices as non-tariff barriers (NTBs) to American internet services. In a submission for the upcoming 2026 National Trade Estimate Report on Foreign Trade Barriers, the company argues that foreign anti-piracy mandates are inadvertently choking digital commerce and establishing dangerous precedents for online censorship.
This move marks a significant escalation in the debate over intellectual property enforcement, pitting content rightsholders - who lobby for expanded blocking - against core internet service providers who prioritize an open, functional, and global internet.
The Argument: Censorship Infrastructure as a Trade Barrier
Cloudflare's central argument is that the infrastructure built for "anti-piracy" blocks is an easy-to-use 'kill switch' for censorship, which fundamentally hinders the ability of US digital service providers to operate internationally. By framing these national content restrictions as NTBs, Cloudflare is attempting to leverage the full weight of US trade policy to dismantle the blocking mechanisms.

The submission specifically highlights systems that lead to:
- Massive Overblocking: The company points to Italy's automated "Piracy Shield" system, which has been repeatedly criticized for its blunt, overzealous application. Using shared IP addresses for blocking, this system reportedly led to the "massive-scale overblocking" of "tens of thousands" of legitimate, non-infringing websites, including charities, telecoms, and schools, as reported in various incidents where Cloudflare's shared IPs were targeted.
- Overbroad Blocking Mechanisms: Similar concerns were raised about wide IP-blocks in Spain and new, automated blocking plans in France. Cloudflare argues that these broad, automated mechanisms fail to adhere to basic principles of proportionality and due process, creating economic damage for legitimate US businesses that rely on these infrastructures.
Beyond Piracy: The Threat of Collateral Damage and Censorship
The core danger, according to Cloudflare, lies in the technical mechanisms themselves. Site blocking is typically implemented at the DNS (Domain Name System) or IP (Internet Protocol) address level.
- Shared IP Addresses: Modern internet infrastructure often relies on shared IP addresses for many services, especially Content Delivery Networks (CDNs) like Cloudflare. Blocking one IP address because a single domain on it is accused of piracy can instantly take down hundreds or even thousands of unrelated, legitimate websites hosted on that same IP. This "collateral damage" is the operational proof that these systems are fundamentally flawed and disproportionate.
- The Slippery Slope of Censorship: Cloudflare and other digital rights advocates have long warned that once the technical infrastructure for rapid, state-mandated internet blocking is in place, it will inevitably be repurposed. The company suggests that these mechanisms are not just for combating piracy or illegal content, but constitute a "convenient censorship lever" that can be - and is - abused by both authoritarian and purportedly "democratic" regimes to silence political opposition or control information flow.

Key Facts and Data
Cloudflare is essentially asking the USTR to acknowledge that the right of a US company to provide its services globally without excessive, disproportionate foreign regulation is a matter of trade, not just intellectual property law. By forcing a trade discussion, they aim to mobilize the US government's leverage to promote a truly open internet and dismantle what they see as a burgeoning global censorship apparatus disguised as anti-piracy enforcement.
