When a website's WHOIS record literally doesn't exist and there's no about page or contact info anywhere, you're essentially dealing with a ghost. That's the situation with cdn.bighappy.co, a subdomain hosted on AWS CloudFront that appears to serve as a content delivery endpoint. While the technical infrastructure itself is fine — clean Google Web Risk status, valid encryption, fast load times — the total absence of identity and transparency is a serious problem.
For a CDN subdomain, some anonymity might be expected if it's a backend asset host for a legitimate company. But the lack of any real-world presence, combined with zero web archive history and no way to reach a human, means you have no recourse if something goes wrong. Legitimate businesses operating CDNs still have parent companies you can look up. Here, there's nothing.
If you've been directed to this domain by another site or service, you should treat that referring party with deep skepticism until you can verify who actually runs it. Until then, cdn.bighappy.co gets a Dangerous rating from us — not because it's been caught doing anything malicious, but because you can't even find out who's behind it.
