CertCentral: Automatic DCV checks – DCV polling

We are happy to announce we've improved the domain control validation (DCV) process and added automatic checks for DNS TXT, DNS CNAME, and HTTP practical demonstration (FileAuth) DCV methods.

This means, 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 cadence

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 have not 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 will need to run the check yourself.
