Build your own CDN on AWS with Route 53
instantdomainsearch.com

Also, there's no need to use Route 53, you can get GeoDNS running under bind with a source patch.
CloudFront only has a couple dozen edge locations: https://aws.amazon.com/about-aws/globalinfrastructure/region...
The real beauty of this setup is that the app server is also geographically distributed, and the flexibility to do whatever you want like support SPDY.
Route 53 is convenient because it integrates nicely with other AWS resources.
