Hello, Today, OONI published a *new research report* documenting *widespread collateral damage caused by IP blocking in Spain during LALIGA football broadcasts* over the past 6 months. Read our report here: https://ooni.org/post/2026-laliga-collateral/ Key findings include: * *At least 5.8% of the internet’s most popular domains were found to be blocked in Spain. *Out of 9.2 million domains tested, we found at least 554,510 domains blocked at some point in time in Spain during the LALIGA football match broadcasts. * *Affected domains include benign and important websites*, such as those of Amnesty International and Greenpeace. * During most LALIGA broadcasts on multiple networks in Spain, *blocking just 4–20 IP addresses in a 1-hour window led to significant collateral damage*, affecting over 400,000 unique domains. * During LALIGA match broadcasts in Spain, *IP-level blocking affected at least 36 infrastructure and hosting providers*, with OONI data identifying 7,441 unique blocked IP addresses associated with major providers including Amazon, Cloudflare, Alibaba Cloud, Akamai, Meta, and Microsoft. * *We detected TLS Man-in-the-Middle (MitM) attacks on Digi Mobil (AS57269), raising privacy and security concerns. *OONI data reveals that a total of 7,334 unique IPs in 14 ASNs, hosting a total of 10,759 domain names, were affected by TLS MitM attacks during the LALIGA broadcasts. * *Blocking implementation varied across ISPs*, with Telefonica among the most consistently observed operators applying the blocking. * *Blocking by most ISPs was largely confined to LALIGA match time windows*, with minimal evidence of spillover outside broadcast periods. Although the impact estimated in our study is already substantial, our methodology is a lower bound, meaning that the *true extent of the impact is likely higher* than our reported figures. We believe this *raises questions about the necessity and proportionality of blocking such a large portion of the web in the context of copyright enforcement against unauthorized football streams*.
