Npm audit seems to be blocking Travis

My most recent build is failing with this error:

npm ERR! audit Your configured registry (https://registry.npmjs.org/) may not support audit requests, or the audit endpoint may be temporarily unavailable.

npm ERR! audit The server said:

Access denied | registry.npmjs.org used Cloudflare to restrict access
You are being rate limited
The owner of this website (registry.npmjs.org) has banned you temporarily from accessing this website.

Is anyone else seeing this? Restarting the build shows the same message. Not sure who we need to poke to get Travis’s IP ranges whitelisted?

Looks linked to this: https://github.com/npm/cli/issues/836

Apparently, they have a reason to think that automated use of audit like this disproportionally loads their service at the expense of its manual users thus are blocking such attempts.

It looks like you can log in to get higher rate limits corresponding to your account.
