First blaming tailscale, dns configuration and all other stuff. Until I just copied that above URL into my browser on my laptop, and received a website banner:

For those non-spanish speakers: It means there is football match on, and during that time that specific host is blocked. This is just plain madness. I guess that means my gitlab pipelines will not run when football is on. Thank you, Spain.
Every response and comment from LaLiga, the football organization responsible for this, has been so far that this is a minor issue that only affects a few bunch of nerds who talk about "docker images" or "github repositories" or "whatever that means".
Meanwhile, there are testimonies of smart home devices like anti-theft alarms or automatic doors, that stop working whenever there is a football match, because their backends rely on Cloudflare.
Last week, a woman asked for help on social media, as the GPS tracking app she uses to see where her father with dementia is, went offline during a match. It was getting late and he still wasn't back home, and she couldn't locate the tag he was wearing to find him: https://www.infobae.com/america/agencias/2026/04/05/laliga-d...
It's hard to say this, because no one should experience an event like this, but as stressful as these are, it's the only way to make the mainstream people care about this censorship. "I cannot pull a docker image" will never be on nightly news, but safety and personal security is a more powerful driver for discourses.
The real fix on your end until Spain sorts this out: set up a pull-through registry cache (e.g. registry:2 with proxy.remoteurl) on a VPS outside Spain, and point your Docker daemon's mirror config at it. Your
GitLab runner pulls from the cache, the cache pulls from Docker Hub via a non-blocked IP. Also insulates you from Docker Hub rate limits.
But yeah, the fact that a court order about football streaming can break docker pull for an entire country is genuinely absurd.When the La Liga match starts, everything that's proxied via CF (including zero access reverse tunnels) stops working.
There's even a website made for checking if the match is on: https://hayahora.futbol/
You can check if your host is affected: https://hayahora.futbol/#comprobador&domain=docker-images-pr...
Looks like same old regulatory capture.
Or can this be avoided by using an alternate DNS?
Big companies don't hide their VPN ASNs. Obscure, for sure, but getting a good list isn't hard. Usually they get blocked.
Smaller companies may pass under the radar, and have higher tolerance for risky strategies.
The fringe providers are the problem. They aggressively change IP ranges, front-vs-obscure ownership, and play dirty. Shady folks will resell residential ranges. End-users often get tainted goods.
... and you still have the collateral damage game when VPNs host infra with big cloud providers vs colofarms vs self-host, etc.
And even if you managed to get them all beforehand, some VPN providers will adapt and keep some servers in reserve, putting them online just as you managed to block the previous ones. Getting around internet censorship is a large chunk of their business, and some are really good at it.
Yes, they block IPs belonging to CDNs (CF including R2, BunnyCDN, CDN77, Fastly, Alibaba, Akamai even)...
But come on, this can't be true. I wonder how many other people in IT wasted hours on issues and tickets to find out it is due to a football match taking place. Admittedly, chances are low, as football matches are usually outside of office hours.
What Spain does is basically censorship and it's very poorly executed. The docker image registry is only one out of the many collateral victims of this stupid law.
This is not an issue under the civil code (civilian issues), but something to be dealt under penal (criminal) code.

Oh, and BTW, LaLiga has just partnered with a CF rival.
Now CF can just sue both like hell because of unfair competition:

So, if you want them to build stuff, ask yourself, are there any "Docker Registry" startups out there. If jsdelivr/globalping is not keeping you busy enough... there is an idea
Globalping and jsDelivr took years to gain a meaningful user base
