Hi all, apologies for opening a new topic. The earlier thread is closed, so I hope it is alright to ask again a few months on:
Since February, two publicly trusted CAs now offer dns-account-01 in production:
- Certainly: A Smarter ACME Challenge for a Multi-CDN World | Fastly
- Google Trust Services, announced this month: July 2026 - Google Trust Services Supports ACME dns-account-01 Challenge | Public Key Infrastructure | Google for Developers
Given that the Boulder implementation contributed by Certainly is already in place, may I ask whether Let's Encrypt would be open to enabling dns-account-01, and if so, whether anything in particular is still standing in the way?
Thanks very much for all your work.
