cache.amp.vg isn't a typical website. When you visit it, you just get a 404 Not Found error. That makes it impossible to evaluate as a normal business or service. The domain's ownership is a mystery — the WHOIS lookup returned nothing, meaning the domain may not be registered at all or is fully hidden. There's no contact info, no about page, and no history on the Wayback Machine. On the plus side, the site isn't blacklisted and has a valid security certificate. But for any practical purpose, cache.amp.vg doesn't actually deliver a web page. If someone sent you here expecting something functional, it's likely a mistake. There's not enough evidence to call it a scam, but there's no reason to trust it either. Is cache.amp.vg fake? Probably not malicious, but with zero content and zero ownership info, it doesn't deserve the benefit of the doubt. Treat it as suspicious until proven otherwise.
