Automatic domain control validation checks

DCV polling for DNS TXT, DNS CNAME, and HTTP practical demonstration/File DCV methods

Automatic domain control validation (DCV) checks, also referred to as DCV polling, removes the need to run the validation checks yourself when using the DNS TXT, DNS CNAME, and HTTP practical demonstration/File DCV methods.

Once you've placed the fileauth.txt file on your domain or added the random value to your DNS TXT or DNS CNAME records, you don't need to worry about signing in to CertCentral to run the check yourself. We will run the DCV check automatically. Although, you can still run a manual check, when needed.

DCV polling

After submitting your public SSL/TLS certificate order, submitting a domain for prevalidation, or changing the DCV method for a domain, DCV polling begins immediately and runs for one week.

  • Interval 1—Every minute for the first 15 minutes
  • Interval 2—Every five minutes for an hour
  • Interval 3—Every fifteen minutes for four hours
  • Interval 4—Every hour for a day
  • Interval 5—Every four hours for a week*

*After Interval 5, we stop checking. If you haven't placed the fileauth.txt file on your domain or added the random value to your DNS TXT or DNS CNAME records by the end of the first week, you'll need to run the check yourself.
