🔴 New report: Collateral Damage of IP-Based Blocking During LALIGA Football Streaming in Spain: Evidence from OONI Measurements ooni.org/post/2026-la... Our latest report documents widespread collateral damage caused by IP blocks in #Spain during LALIGA football broadcasts over the past 6 months.

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 (including @amnesty.org) at some point in time in Spain during the LALIGA football match broadcasts. ooni.org/post/2026-la...

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. ooni.org/post/2026-la...

At least 36 infrastructure and hosting providers were impacted by the IP-level blocking observed during LALIGA match broadcasts. OONI data from #Spain reveals the blocking of 7,441 unique IP addresses belonging to 36 organizations (e.g. Amazon, Cloudflare, Alibaba Cloud). ooni.org/post/2026-la...

‼️ We also detected TLS Man-in-the-Middle (MitM) attacks on Digi Mobil (AS57269), raising privacy and security concerns. OONI data from Digi Mobil in #Spain reveals that 7,334 unique IPs in 14 ASNs, hosting a total of 10,759 domain names, were affected by TLS MitM attacks. ooni.org/post/2026-la...

OONI data from #Spain shows that blocking implementation varied across ISPs. Blocking by most ISPs was largely confined to LALIGA match time windows, with minimal evidence of spillover outside broadcast periods. ooni.org/post/2026-la...

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. Learn more: ooni.org/post/2026-la... We thank OONI Probe users in #Spain for contributing measurements. 🙏
