Some context the article misses: there's a court order that allows the Spanish Football League to block websites which may be unlawfully broadcasting football, and the ISPs have to comply. Since Chrome activated ECH, LaLiga requested the order to be expanded to block individual IPs, to which the court happily obliged, and this order is being used to block Cloudflare's IPs ranges.

The result is that web browsing in Spain on weekends, when football is on, is severely impaired, with thousands of web sites going down as matches play. This is a breach of the court order itself, which clearly states that "no unrelated sites may be affected", all while the court order itself probably being illegal as well. And, of course, IPTV pirates found ways around the block.

bandaancha.eu is doing a fantastic job on the reporting of this.
