As of this morning, all CI jobs based on node 6 are failing on npm install. This affects both npm-node-6-docker and (presumably) all of the -deploy-npm-node-6-docker jobs.
Example from https://integration.wikimedia.org/ci/job/mobileapps-deploy-npm-node-6-docker/206/console:

I believe this is happening because the npm version used (v3.8.3) has somehow become insufficient. I was able to reproduce locally by running npm install with v3.8.6. However, npm v.3.10.8 is able to complete the install successfully.
