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](https://docs.google.com/forms/d/e/1FAIpQLSex-tMRcNBMZS9zBcu2aKhlWZq94nlrJqo-LHlLOW2yUs3gIQ/viewform?usp=header_link).

If you are experiencing issues with DNS validation, visit our
[DNS Debugging page](https://developers.google.com/public-key-infrastructure/dns-debugging) for help.
