Why does the Internet Archive only work with a US IP address?

any1: > e using a European Mullvad exit. What VPN do you use? I am currently on a family member’s Nord account. They rarely use it, so I didn’t want to waste it. I know Nord is not recommended by the privacy community. This is just a temporary situation. I only use it on desktop. On mobile, I am on Proton. I often add articles to read later on Raindrop. If I add an archived link from a non US IP, I am not able to read it there. But if I add it from a US IP, open the article in Raindrop, then switch back to my preferred non-US IP, I am able to read the article.
