Proxy / ECONNRESET issue

Hi there,

After installing the trying to run a deployment, my deployment log wigs out and reports a whole series of proxy errors.

E.g.

```
npm ERR! network read ECONNRESET
npm ERR! network This is most likely not a problem with npm itself
npm ERR! network and is related to network connectivity.
npm ERR! network In most cases you are behind a proxy or have bad network settings.
npm ERR! network
npm ERR! network If you are behind a proxy, please make sure that the
npm ERR! network 'proxy' config is set properly. See: 'npm help config'
npm ERR! Windows_NT 6.2.9200
npm ERR! argv "D:\\Program Files (x86)\\nodejs\\0.12.6\\node.exe" "D:\\Program Files (x86)\\npm\\3.3.9\\node_modules\\npm\\bin\\npm-cli.js" "install" "--no-optional" "--no-bin-links" "ember-cli"
npm ERR! node v0.12.6
npm ERR! npm v3.3.9
npm ERR! code ECONNRESET
npm ERR! errno ECONNRESET
npm ERR! syscall read

Any thoughts? I can post more info / logs if it helps.
