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.

Or can this be avoided by using an alternate DNS?

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.

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.

But anyone who is pulling docker images in a sunday afternoon while the rest of the country is glued to their screen to watch a football game or enjoying a sunny sunday outside having beers and tapas and what not should be capable of setting up wireguard.

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.
