Array.io has been around since 2012, but that history doesn't mean much when a domain is days away from expiration. The site immediately redirects visitors to array.com, which means array.io functions more like a forwarding address than a standalone business. If you've landed here expecting to find a company, you'll be sent elsewhere before you even see a page.
For a redirect domain, the trust question is really about why it exists and whether it'll still work next week. The technical side is fine: the connection is encrypted, the mail servers are set up properly, and there's no malware or blacklisting. But the impending expiry and the lack of any historical snapshots in the Wayback Machine are genuine concerns. Whoever owns it hasn't bothered to leave a mark, and they haven't renewed the registration yet.
If you're considering array.io for any reason, your first question should be: why does this domain redirect instead of hosting its own content? And if you're relying on it as a link or an email address, check back after the expiration date to see if it's still active. For now, treat it as uncertain territory.
