Did someone change my DNS records?
Updated 2026-10-16
Short answer: a single DNS change can take down a website or email, and DNS is often edited by more than one person: you, a developer, an agency, or a tool that "just needs one record". If nobody tells you, the first sign is the site or email breaking.
How to check it yourself
- In the Cloudflare dashboard, open Manage Account, then Audit Log, and filter for DNS record changes.
- Note what changed, when, and by whom.
- Compare your current records with a known-good list. Export one now from the DNS page so you have it next time.
- Ask whoever made an unexpected change what it was for before you undo it.
What Preventionlabs shows
With a read-only Cloudflare token connected, Preventionlabs takes a snapshot of your DNS records every hour and reports any record added, removed or changed since, with the time. For example, from a real report: "changed CNAME dceaustralia.com: dceaustralia.pages.dev -> dce-lab.pages.dev". It also shows other changes made in the Cloudflare account in the last 72 hours, from its change log.
