cdnjs.com, 542 js libraries served by CloudFlare CDN

CloudFlare, Sh*ts

http://cdnjs.com/ hosts an HUGE LIST of js libraries  – 542 – served by CloudFlare CDN!
Hooray!

Everyone loves the Google CDN right? Even Microsoft runs their own CDN.
The problem is, they only host the most popular libraries.
We host it all – JavaScript, CSS, SWF, images, etc!

(..)

At CloudFlare, we believe that open source, community-driven projects like CDNJS are the tools upon which the future of the internet will be built. CloudFlare is proud to provide the global CDN infrastructure that will help power that future.

“From: Jeremy
Subject: Do you pass the real webhosting IP to search engines?

Hello Matt,

Thank you for contacting CloudFlare.

We have registered our IPs with Google and Bing as a CDN provider to prevent a negative impact to your page rank. Major crawlers do not penalize for IP changes if they are from a CDN since those IPs change very frequently.

No, we do not pass the source IP of your origin server to crawlers. There is no standardized way to do so. Crawlers only know the IP that your domain resolves to, which would be CloudFlare IPs if the service is active.

Let us know if you have any other questions.”
