The Twitter Bootstrap CDN was distributed at Bootstrap CDN.

Currently, version 3.0.0 is set as the default, but of course past CDNs are also distributed as shown below.

The speed is slightly lower when using a CDN, but it is nice to be able to use it affordably for development, etc.

I'll use it next time.
