Installing any old package that has zone@0.3.4 (the latest) as a dependency (direct or transitive) will fail due to this package's (unnecessary) attempt to contact `blip.strongloop.com`, which doesn't even exist in DNS any more. In my case, trying to get the docs from an old version of AWS Amplify (aws-amplify@3.3.20) was impossible because of the dependency (`aws-amplify@3.3.20 -> @aws-amplify/ui-angular@1.0.2 -> zone@0.3.4`). ``` error Error: getaddrinfo ENOTFOUND blip.strongloop.com ```
