NPM install failing with 502 error

This is a problem with the registry.npmjs.org in some regions.

Here is issue: https://github.com/npm/npm/issues/13284

I'm seeing the same issue via npm install on Ubuntu 14 running on AWS

curl https://registry.npmjs.org/combine-lists/-/combine-lists-1.0.0.tgz

returns 502 Bad Gateway from the ubuntu server, but works fine from local client

There's an open issue at NPM for this:

NPM just acknowledged the issue and they are working on it. Your can track the status at below link.
