This domain is supposed to be a CDN infrastructure site, but right now it doesn't serve any content at all. Visiting smart-digital-cdn.com just gives a 404 error β the resource doesn't exist. That's a clear sign the site isn't maintained. Most CDN or hosting domains you'd actually want to use have active web interfaces or at least a placeholder page. The domain is six years old, which normally suggests stability, but it expires in less than a month, and the lack of any Wayback Machine history over those six years is odd. It may have been used internally or for a short-lived project, but for any practical purpose today, it's unavailable. No malware or blacklist flags, so we're not calling it a scam, but it's also not something you can rely on. If you're asking whether smart-digital-cdn.com is fake or just inactive, the answer is the site doesn't function β so treat it as out of service until proven otherwise.
