According to the Apple Support forums, it looks like a fix for this is to comment out gs.apple.com in your hosts file. 

Comment it out in /etc/hosts by doing the following (taken from that page):


Open Finder
Hold down COMMAND + SHIFT keys and press 'G'
Enter "/private/etc/" in the field and press "Go"
Find "hosts" file in the directory
Drag the file to your desktop
Open it in text editor
Remove the line that has gs.apple.com entirely or put a # at the beginning of it to comment it out
Save the file
Drag it back to the /private/etc/ folder.
