I cannot download the CirrusAssets.zip file required for the Site.com Workbook.

The link in the workbook is:

http://www.salesforce.com/us/developer/docs/siteforce/CirrusAssets.zip

Which redirects me to:

https://developer.salesforce.com/docs/atlas.en-us.siteforce.meta/siteforceCirrusAssets.zip

Both links lead me to a blank page.

Can I have a working link to download the zip file?

Thank you
