One of the things I do like about Cloudflare though is their global CDN capabilities.  Im legitimetly interested in your DDoS Protection; however, many of my sites receive traffic worldwide on a rather routine basis so CDNs that offer facing on regional servers is ideal. 

Is your datacenter for the DDoS protection a single location or multiple spots and does it offer any CDN?  Is it easily implemented with CDN networks.  Please elaborate.
