NPM registry alternative to http://registry.npmjs.org/npm

Update: Every URL in this post is expired, sorry

Just found this link that lists some mirrors:

http://blog.modulus.io/npm-mirrors

The listed ones as of this writing are:

• http://registry.npmjs.org
• http://registry.npmjs.eu
• http://registry.npmjs.org.au
• https://registry.nodejitsu.com
• https://npm.strongloop.com

Specify the registry when installing:

$ npm install --registry http://registry.npmjs.org

Or update the registry permanently in the config:

$ npm config set registry http://registry.npmjs.org

There aren't any public alternatives, that I know of. At my company, we ended up doing an internal mirror, where we also publish our internal NPM packages.

I'm told it's not quite trivial - but definitely doable.
