This domain isn't the kind of site you'd browse or buy from. It's a server address used by Google's video infrastructure — think YouTube or other streaming services. The 404 error you see is normal: direct access isn't intended.
From a trust perspective, the signals are clean. The SSL certificate is valid and modern, the server isn't on any blacklists, and the parent domain has an impeccable reputation. There's no evidence of phishing or malware.
If you're wondering 'is rr1---sn-2uuxa3vh-3ovs.gvt1.com a scam?', the answer is no. It's simply a backend component. Most users will never interact with it, and there's no risk in doing so. It's a good reminder that not everything on the web is a standalone business — sometimes it's just infrastructure doing its job.
