Hi everyone,
I'm running OSX Mountain Lion 10.8.2 and I have just created a brand new subdomain in cPanel. I load it up in Firefox, Chrome, Opera and it doesn't show up at all. Just gives the standard message, "can't find page". I try clearing DNS using Terminal (sudo dscacheutil -flushcache), clearing cache in the my browsers, deleting all history and preferences in my browsers, going to OSX Preferences -> Network -> Renew DHCP Lease... Nothing works. So I talk with my hosting provider and they have no clue. They are able to see the subdomain without any problems and figure it may be ISP related.

I try my iPhone using 3G (different ISP) and it displays fine. What the heck! Then I try loading Parallels VM, Windows 8, IE10 and it too loads fine. This is using the exact same ISP as Mountain Lion is. Very strange...

Now I try Safari in OSX (the last browser to test) and it too loads fine! .. OK so this means that Firefox, Chrome, and Opera are not letting me see the new subdomain, but Safari of all browsers is...

Has anybody else run into this issue before too? I would really like to get the subdomain working instantly as soon as I create it in cPanel in all of my browsers so that I can browser test any new design work.

Thank you,
