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
