We got burned by CloudFront about 18 months ago... we were serving our static assets (CSS, JS etc) through CloudFront and had bug reports from some users in eastern europe (I forget where, it might have been Slovenia) that our site was displaying without CSS. I got them to check and they couldn't load CSS for GitHub (which used CloudFront) either. We went back to serving directly from S3.
It's an infuriating bug, because I can't see how we could confirm that this kind of thing isn't an issue any more. I'd love to go back to CloudFront but I'm just not confident that it will reach all of our users.
