When I got to http://apple.com, the page loads fine and perfectly. But when I click on a link (or type it in) to go another part of the website, it refuses to load. Safari 4 tells me it is 'contacting apple.com', but it never actually starts loading the webpage. When I try Firefox it gets stuck on 'watiing for apple.com'.
Every other website (apart from adobe.com) works fine.
It is a massive pain and I would love to get to fixed soon. What methods should I take to try and fix it?
