I trid out CloudFlare for a few months for a couple of my sites. I was primarily interested in their 'no downtime' feature but could never get it to work for me. I ended up swtiching to S3 and CloudFront, paying a little each month but it actually works.

Their no down time feature is just them holding a cache'd copy of your site. It could technically not work for you and still work for someone else.
