Dear GlobalSign Customer / Partner,

Over the second half of 2021, two changes in domain validation policy will take effect, which may impact how you validate domains when issuing publicly trusted TLS certificates. These policy changes apply to all new certificate requests, renewals, re-issues and pre-validated domains. These changes will have NO IMPACT on TLS/SSL certificates that have already been issued.

- Domain revalidation will be required every 397 days instead of every 825 days - Issuance of wildcard and subdomain SANs will be prohibited for domains validated via the HTTP method

For more information on these upcoming changes, please view this blog post.
