rr2.sn-bg0s7ns7.googlevideo.com is a subdomain of googlevideo.com, part of Google's video-serving infrastructure. But that doesn't mean you should expect it to work like a normal website. The real issue is that the SSL certificate doesn't match this particular hostname. Any visit will throw a security warning, and the page itself returns a 404. That means you can't actually see anything here, and your browser will actively flag the connection as unsafe. For a server that's supposed to deliver video content reliably, this is a serious configuration failure. The domain isn't on any blacklists, which suggests it's not malicious, but the technical problems make it effectively unusable. If you're trying to access a video that routes through this server, you might hit an error or a security block. There's no customer support to contact and no privacy policy, because this isn't a consumer-facing site. The best advice: steer clear. There's nothing useful here, and the security error alone is reason enough to leave this address alone.
