If you've come across edge-138.usuyk1.ce.apple-dns.net and wondered whether it's safe to visit, the short answer is no. This isn't a consumer website — it's a technical subdomain on Apple's infrastructure that returns a 400 Bad Request error and has an SSL certificate that doesn't match the address. The server is reachable only as a machine endpoint, not a page you can browse.
There are no edge-138.usuyk1.ce.apple-dns.net reviews because there's nothing to review. No contact page, no about page, no privacy policy. The site is essentially invisible to the web. The certificate is valid for a different Apple service (api-edge.icloud.com), which suggests this hostname is an internal routing label, not something meant for the public.
If you're asking 'is edge-138.usuyk1.ce.apple-dns.net a scam' — the evidence doesn't point to a scam, but it does point to a URL that has no business being used as a website. Treat it as a non-functional address and move on. There's no reason to trust it with your data or your attention.
