It's not linked on their download page, but give this link a shot:
I just guessed the filename and it seemed to work.
UPDATE: Oops! Looks like it's just a 15-byte filename with the text contents "File Not Found"
Anyone have a preview download link?
You could also type 9.56.13 and will receive this file.
The final release is not ready yet.
I'd say a few folks are hitting it - *grin* akamai have dropped even their 'file does not exist' page on that one....
