Cloudflare has officially appealed to the Spanish Constitutional Court, opposing sweeping anti-piracy measures implemented by LaLiga and Telefónica. The appeal follows months of IP address blocking that has unintentionally disrupted access to legitimate online services across Spain.
Growing Fallout from Spain’s IP Blocking Campaign
Since February 2025, LaLiga and Telefónica have been blocking IP addresses during football matches in a bid to stop illegal sports streaming. The crackdown, however, has had unintended consequences: numerous legitimate domains—including Google Fonts, public institutions, and payment platforms—have also been affected.
Cloudflare, a U.S.-based leader in content delivery (CDN) and DNS services, is now pushing back. The company argues that these enforcement tactics are not only imprecise but deeply harmful to regular internet users and online infrastructure.
Cloudflare Speaks Out on “Problematic” Measures
“Blocking an IP used by thousands or even millions of domains creates extensive collateral damage,” said Alissa Starzak, Cloudflare’s Vice President and Global Head of Public Policy, in a statement to TechRadar. “The tactic may target one infringing site, but ends up affecting countless legitimate services.”
Starzak emphasized that shared IPs are common among DNS providers. A single IP address might host a multitude of unrelated websites. Blocking that IP means all those sites become inaccessible—regardless of their legality.
Widespread Disruptions Confirmed
One of the most prominent examples of unintended disruption is Google Fonts, the widely-used cloud-based font service relied upon by millions of websites. Users began reporting issues with Google Calendar, YouTube, and other services relying on Google Fonts due to IP-level blocking.
The disruptions appear to have primarily affected users of Digi and Vodafone, who confirmed to Spanish media that the block was enacted following a request from Telefónica on May 27, 2025.
These incidents fueled growing frustration among affected users and intensified scrutiny of Spain’s anti-piracy practices.
Public Criticism from Cloudflare’s CEO
Matthew Prince, Cloudflare’s Co-founder and CEO, voiced strong opposition to Spain’s IP blocking approach. In a public post on X (formerly Twitter), he described the strategy as “bonkers.”
“The collateral damage is vast. It’s only a matter of time before a Spanish citizen is denied access to a life-saving emergency resource because a football rights holder wants to block an IP,” Prince warned.
He criticized the indiscriminate nature of the blocks and accused LaLiga of prioritizing copyright enforcement over citizen access to essential online services.
Legal Challenge Heads to Constitutional Court
On May 19, 2025, Cloudflare filed a formal appeal with Spain’s Constitutional Court. The company aims to prove that the current enforcement framework lacks legal justification and causes disproportionate harm to innocent parties.
“They told the court there would be no collateral damage,” Starzak noted. “That’s obviously false. Even though these orders technically expired with the football season, we believe it’s vital to challenge the underlying legal basis.”
LaLiga Accuses Cloudflare of Enabling Piracy
LaLiga remains defiant. In an official statement issued on February 15, 2025, the league accused companies like Cloudflare and Google of “actively enabling illegal activities.” They claimed that tech firms facilitating piracy are profiting from digital fraud.
“LaLiga, with the backing of the justice system, will continue to defend football and club interests against criminal actions,” the organization stated.
A Wider Anti-Piracy Battle in Europe
Cloudflare’s legal battle in Spain is part of a broader European trend toward more aggressive anti-piracy enforcement. In France, a landmark ruling from the Paris Judicial Court on May 15, 2025, ordered five major VPN providers—NordVPN, ExpressVPN, Surfshark, Proton VPN, and CyberGhost—to block access to over 200 illicit streaming websites.
France’s Canal+ has led this charge, following previous wins targeting DNS services. Similar measures are being discussed in Italy, Portugal, and Belgium, where governments are considering legislation to expand blocking obligations to VPNs, CDNs, and DNS providers.
Streaming giants across Europe are also lobbying the European Union to impose stricter requirements on digital intermediaries, hoping to enlist more tech firms in their fight against piracy.
Spain Remains Cloudflare’s Top Priority
Despite the international escalation, Cloudflare continues to focus its legal efforts on Spain, where the scale of collateral damage has been most significant.
“If policymakers believe they can enforce broad IP blocks without considering everyday users, that’s a serious issue,” said Starzak. “We need the EU to understand that blunt instruments like IP blocking can cause lasting harm to the free and open Internet.”
Cloudflare is committed to preventing such sweeping enforcement methods from becoming normalized. As the next sports season approaches, the company hopes its legal challenge will lead to a more balanced, technically sound solution that respects user rights while addressing piracy concerns.
Shared IP Infrastructure and the Risk of Overblocking
Cloudflare’s core concern lies in how shared IP infrastructure works. A single IP address often serves thousands—or even millions—of unrelated domains. When ISPs block that IP due to one infringing site, all other services hosted behind it become inaccessible. This leads to widespread collateral damage, disrupting access to essential tools like fonts, payment portals, and even government resources. Such disruptions can erode trust in internet reliability and highlight the flaws of blanket blocking tactics.
Legal Ramifications of Spain’s Anti-Piracy Strategy
The legal framework under which LaLiga and Telefónica are acting has raised alarms among digital rights advocates. Cloudflare’s appeal challenges whether these broad IP blocking orders comply with Spain’s constitution, particularly regarding proportionality and due process. By bringing the matter to the Constitutional Court, Cloudflare is not only seeking relief for its own network but also aiming to set a legal precedent against the misuse of IP blocks for copyright enforcement.
Impact on End Users and Digital Services in Spain
The unintended fallout from Spain’s current anti-piracy enforcement has reached ordinary users. People have reported issues accessing Google services, university websites, and secure payment platforms—all vital in everyday life. As digital services increasingly rely on cloud infrastructure and shared IPs, indiscriminate blocking doesn’t just affect piracy—it interferes with public access to information, education, commerce, and communications.
🇪🇺 Implications for EU-Wide Internet Policy and Future Regulation
Spain’s situation may be a testing ground for the European Union’s broader stance on digital regulation. With France, Italy, Belgium, and Portugal exploring similar blocking frameworks, the EU could soon face pressure to either standardize or restrict these practices. Cloudflare’s case highlights the need for carefully crafted policies that target piracy without undermining the functionality of the open web. The resolution of this case may shape how DNS, CDN, and VPN services are governed across the continent.
Technical Limitations of IP-Based Blocking in the Modern Internet
IP-based blocking is increasingly seen as an outdated method for regulating online content. In today’s cloud-based web infrastructure, where thousands of domains can share a single IP, blocking that address can unintentionally affect countless unrelated services. Cloudflare emphasizes that modern anti-piracy strategies should be domain-specific or content-specific, rather than relying on blunt instruments that disrupt the wider internet ecosystem.
Calls for Dialogue Between Tech Providers and Rights Holders
Cloudflare has urged rights holders like LaLiga and enforcement bodies to engage in more transparent and cooperative dialogue with infrastructure providers. Rather than imposing broad, legally questionable orders, Cloudflare advocates for targeted enforcement through collaboration. By developing more precise tools and sharing data responsibly, both parties could achieve piracy reduction without compromising digital access or public trust in the web.
