cmsasset.ancestrycdn.com isn't a website you browse β it's a behind-the-scenes asset server that delivers images, scripts, and other files for Ancestry.com. That explains the "Access Denied" page you see if you try to visit it directly. For its role, the domain checks out: five years of consistent operation, a clean security record, and hosting on Akamai, one of the world's most reputable content delivery networks. There are no signs this server has ever been compromised or blacklisted. If you're asking whether cmsasset.ancestrycdn.com is fake or a scam, the answer is no β it's a legitimate piece of infrastructure from a well-known company. The only thing to watch for is that you're actually visiting the real subdomain; scammers sometimes create lookalike URLs. But as long as you're on the genuine ancestrycdn.com subdomain, there's no safety concern.
