This address belongs to Google's content delivery network, which supports video streaming services. It is normal for such domains to return a 404 error when accessed directly because they are designed to communicate with your browser, not with you.
Most users search for rr15---sn-jvhj5nu-nh4d.googlevideo.com reviews because they are concerned about unexpected activity in their network requests.
