Basically, to combat pirate streaming of football matches, La Liga (the Spanish football association) can compel Spanish ISPs to block wide ranges of IP blocks that are suspected of hosting those streams.
This includes Cloudflare, which - due to lots of websites depending on them (see what happened when they went down last year: https://blog.cloudflare.com/18-november-2025-outage/ ) feels like half of the internet is unusable. This happens weekly when football is on.
Now it looks like those bans are going to become even more frequent, which will have all kinds of unintended consequences.
If you're on a residential connection, during play of the matches, you can't access any of the Cloudflare IPs, but everything else keeps working as-is. Most businesses already migrated away from Cloudflare once these blocks started happening, so most of the affected people are the ones using services that rely on Cloudflare.
As mentioned elsewhere, don't get me wrong, it sucks, makes no sense and I wish it went away, and I'll keep complaining to the ones I can about it, but "they're cut off from half the internet" isn't accurate unless somehow half the services you use happen to rely on Cloudflare (which, at least for me, isn't true, maybe 10% of what I use daily is affected by this).
It's not a stretch for small businesses to be reliant on residential connections either.
At any rate, this behavior isn't befitting a serious country like Spain.

TL;DR: Spain blocks A LOT of CDNs during footy matches, including ALL of Cloudflare, thus breaking most of the internet. All in the name of stopping "pirates".AFAIK, I don't think it's "A LOT of CDNs", it's only Cloudflare, at least personally Cloudflare is the only CDN I can verify I lose access to during the football matches.
