This domain is a subdomain of googlevideo.com, which is owned by Google and used to serve video content for YouTube and other Google services. It's not a consumer-facing website, so there's no storefront, login page, or contact form. The 404 error you see is a normal response from a CDN endpoint that isn't meant to be browsed directly. For context, most established video delivery networks use structures like this, and Google's infrastructure is among the most secure and reliable. If you're wondering whether rr9---sn-4pgnuhxqp5-jb3ee.googlevideo.com is a scam, the answer is no - it's a legitimate part of Google's backend. There are no reviews for this specific subdomain because it's not a business, but the parent domain has an impeccable reputation. You don't need to worry about safety when visiting this URL; it's just a technical node that streams video when called by a YouTube client.
