What changed

Nothing has changed on npmjs.com since we started watching it.

Certificates expire, DNS gets edited, a header goes missing in a deploy. Prove the domain is yours and we watch it on a schedule — free — and email you the moment something moves, so you hear it from us instead of from a customer.

A certificate that expires on Tuesday should not wait until Friday. Prove a domain is yours and we check it free, once a week, emailing you anything that changed. Pro checks it once a day, looks at every host on the domain, and keeps 365 days of history — so you hear about a problem in hours rather than days.
