Google Trust Services strives to provide the most compatible TLS certificates
available. By default we offer a certificate profile and chain that is optimal
for most use cases. If you are a high volume user, contact your customer
engineer if you want to optimize for a specific use case.
If you encounter a compatibility issue with a GTS certificate, let us know about
it using our compatibility report form.
If you are experiencing issues with DNS validation, visit our
DNS Debugging page for help.
