If you're wondering whether rr2---sn-xm2voxoup5ax-aigl.googlevideo.com is a scam or fake, the short answer is no. This is a subdomain of googlevideo.com, which is owned by Google and powers video delivery for YouTube. The 404 error you see when visiting it directly is normal — these servers aren't meant to be browsed like a regular website. They exist to serve video chunks to your browser when you watch YouTube.
So is rr2---sn-xm2voxoup5ax-aigl.googlevideo.com legit? Absolutely. The infrastructure signals are solid: strong encryption, no blacklisting, and fast performance. Don't let the missing contact page or privacy policy worry you — those are irrelevant for a content delivery server. The only thing you might notice is that it blocks search crawlers, which is standard for video servers. In short, this is a trusted piece of Google's network, not something to be suspicious of.
