Hey guys, I run the project jsDelivr which is a free open source CDN for developers.
The main feature of it is availability and performance. We operate a big system that offers as much availability as possible utilizing smart multi-CDN routing.
You can read about it in our repo https://github.com/jsdelivr/jsdelivr and on Mozilla Blog https://hacks.mozilla.org/2014/03/jsdelivr-the-advanced-open-source-public-cdn/
Its been 2 years since the project launched and today we have a small team of active contributors that help out with different components of the project.
We are also sponsored by companies such as MaxCDN, CloudFlare, Cedexis, Leapswitch, Prometeus and ExpertVM.
