rr2---sn-5fo-c33ls.googlevideo.com is a subdomain of googlevideo.com, which is owned by Google and used to serve YouTube video content. Unlike a typical e-commerce or business site, this is an infrastructure component β a content delivery network (CDN) node. The 404 error you see when visiting the root is completely normal; these servers are not designed to host a webpage. Our analysis found no security threats, no blacklists, and a valid SSL certificate. The server accepts older TLS versions, but that's a common compatibility choice for streaming services. For the purpose of delivering video, this domain is trustworthy. There are no reviews to read because it's not a consumer-facing service. If you're encountering this domain in your browser's address bar, it's likely part of a YouTube video stream β nothing to be concerned about.
