                              The versions hosted on CDNJS seem fine:
                              $ curl -I https://cdnjs.cloudflare.com/ajax/libs/react/15.4.2/react.min.js

                              Maybe it's a good idea to do a HEAD request on the CDN libs at app initialization & fall back to an alternate CDN or local versions of the files if they're not found?
