Our Wix site is not visible from within a corporate internet but is visible outside it. Would it be correct to assume that the corporate's IT has blocked Wix somehow? (this is what we've been told is likely the issue). The site is hosted at Wix & has it's domain name managed by Wix (ie. uses WIXDNS.NET as its nameserver) If this is the case, would changing the registrar solve the issue, or would one need to move both the domain name plus move the hosted content? Does blacklisting affect the domain name or hosted content?
