That side by side comparison you did is the smartest thing in this whole post, because a screenshot alone really does prove nothing, but same link, same phone, two different networks hours apart, that's a real test. My question back to you is how do you even tell the difference between a topic based block and a boring licensing block, since both look identical on the screen. Like if a page about a court case or a health topic gets hit while a random cooking site loads fine from the same network, is that proof, or is it just that one site forgot to renew something. I've seen people swear a page was blocked for what it said when really the site was just down or the CDN threw a fit. So what did the block screen actually say in your Dublin case, did it name a country or a reason, or was it just the vague default page. Because the wording is where the real tell is, if there is one.
