Seeing different websites on different browser for the same domain name?

So I had an old website ( linked to on the multisite. Created a new website ( and linked it to using the domain mapping tool, of course after deleting the old mapping to the old website.

I called paypal and they wanted to verify my website, and they see my old website, broken. How is that so? I linked my domain name to the new website more than 24 hours ago. Caching has been disabled for both websites (caching from Infinite SEO).

Different computers show me the old website. My computer shows the new website. All mobile devices showing the new website.
