Favorite CDN for Rails?

I’ve always used Amazon Cloudfront as a Rails CDN. However, I hear folks talking about other CDNs from time to time. Anybody care to comment on their favorite CDN pick?

The purpose is for my new discourse site: http://talksurf.com.


Cachefly has decent speed but I have had issues with them going down a lot in the past. 10 mins here, 20 mins there hurts on high traffic sites.

MaxCDN (formerly netdna) has been really good and reliable. It’s hard to beat amazon though.

I use AWS CloudFront, and it works well. No need to sync assets, CloudFront handles loading any assets that aren’t already in the cache.
