You've come across p305-quota.icloud.com and wondered if it's safe. The short answer: it's not a scam, but it's also not a functioning website. This subdomain of Apple's iCloud returns a 404 error, meaning there's nothing to see or interact with. The site is hosted on Apple's own infrastructure, with a valid SSL certificate and clean security checks — no blacklists, no malware flags. That's the kind of behavior you'd expect from a legitimate internal endpoint, not a phishing page.
Because there's no content, there's no way for this site to collect your data or trick you into paying for something. The missing contact info and legal pages are irrelevant here — this isn't a business. If you were sent a link to this address, it's probably a broken redirect or an outdated reference. There's no reason to treat it as a threat, but also no reason to return to it. Our advice: ignore it and move on.
