Rackspace CDN Blacklisted by Chrome

I wake up this morning to reports from multiple customers saying that when they try to access a file stored on Rackspace's new CDN product they receive the big red screen that says "The site ahead contains harmful programs".

Rackspace's response: It's Google's fault.

I see the same warning in Firefox.
