Tell HN: docker pull fails in spain due to football cloudflare block

A developer in Spain discovered that Docker pull failures were caused by nationwide IP blocking aimed at illegal football streams, which inadvertently affected Cloudflare's infrastructure used for legitimate tech services.

I just spent 1h+ debugging why my locally-hosted gitlab runner would fail to create pipelines. The gitlab job output would just display weird TLS errors when trying to pull a docker images. After debugging gitlab and the runner, I realized after a while I could not even run "docker pull <image>" on my machine as root:

error pulling image configuration: download failed after attempts=6: tls: failed to verify certificate: x509: certificate is not valid for any names, but wanted to match docker-images-prod.6aa30f8b08e16409b46e0173d6de2f56.r2.cloudflarestorage.com

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:

El acceso a la presente dirección IP ha sido bloqueado en cumplimiento de lo dispuesto en la Sentencia de 18 de diciembre de 2024, dictada por el Juzgado de lo Mercantil nº 6 de Barcelona en el marco del procedimiento ordinario (Materia mercantil art. 249.1.4)-1005/2024-H instado por la Liga Nacional de Fútbol Profesional y por Telefónica Audiovisual Digital, S.L.U. https://www.laliga.com/noticias/nota-informativa-en-relacion-con-el-bloqueo-de-ips-durante-las-ultimas-jornadas-de-laliga-ea-sports-vinculadas-a-las-practicas-ilegales-de-cloudflare

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.

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...
