Sorry, no time to search so if this has been explained kill the thread. I read the staff posting regarding the new DNS change and clearing cookies is good but clearing your DNS cache will actually help more as bad hits are cached so people can still suffer from long load times.

To clear your DNS cache click start, run, type cmd (this will open a command window) and at the prompt type ipconfig /flushdns, you'll get a message that the DNS Resolver has been cleared. Try loading the site again, this is useful also for other sites that take forever to load.
