Cloudflare wants to fix Spain’s blocking of illegal football streams ahead of next LaLiga season
La Liga and Telefonica's IP blocking orders continue to create problems – and Cloudflare has brought its case in front of Spains' Hgher Court
- Cloudflare filed an appeal with the Spanish Constitutional Court over "problematic" anti-piracy measures
- LaLiga and Telefónica have been blocking IP addresses during matches to halt illegal sports streams since February 2025
- Many legit domains, including Google Fonts, institutional sites, and payment platforms, have been affected so far
IP blocking continues to create problems in Spain, and Cloudflare is committed to finding a fix before the new sports season kicks off.
To halt illegal sports streams, Spanish sports streaming giants, LaLiga and Telefónica, have been issuing IP blocking orders since February 2025. Yet, this tactic has led to many overblocking incidents, with Google Fonts, institutional sites, and payment platforms among the legitimate domains mistakenly blocked so far.
Now, US-based major CDN and DNS resolver, Cloudflare, filed an appeal with the Spanish Constitutional Court over what it deems "problematic" anti-piracy measures.
The collateral effect
LaLiga and Telefónica are targeting IP addresses during sports matches to prevent illegal streaming and copyright infringement. An IP address is a string of numbers that acts as a digital address, identifying internet-enabled devices and allowing online communications.
As per La Liga's own declarations, Spain's premier football group has been blocking around 3,000 IP addresses every weekend to contain the damage of copyright infringement.
The problem is that, as with most DNS providers, Cloudflare explained to TechRadar, all of the company's IP addresses are shared.
"In some cases, they have thousands, tens of thousands, hundreds of thousands, or even millions of domains behind them. So, blocking [an IP] because there is a single domain that you want to block, comes with a tremendous amount of collateral damage," Cloudflare's Vice President and Global Head of Public Policy, Alissa Starzak, told TechRadar.
According to Cloudflare, the collateral damage in Spain has been remarkable.
