Has anybody come across the issue of not being able to connect to the iTunes store? I ran a diagnostic provided by iTunes and it says "Secure link to iTunes store failed."

Connection attempt to Apple web site was unsuccessful.
The network connection timed out.
Connection attempt to iTunes Store was unsuccessful.
The network connection timed out.
Secure connection attempt to iTunes Store was unsuccessful.
The network connection timed out.
Secure connection attempt to iPhone activation server unsuccessful.
The network connection timed out.
Last successful store access was 2009-06-19 00:47:04.

This is the last part of my diagnostic. I've port forwarded, not running a firewall, my internet connection's fine and hasn't changed. I can get to any other website just fine including the use of limewire. So I was wondering what I can do to resolve this. If anybody has any idea, it would be of great help. Thank you.
