Hi everyone,

We're excited to announce two new Static Certificate Transparency logs operated by GoDaddy, built on the Sunlight implementation.

Staging logs (Peridot):

Production logs (Aquamarine):

Both logs accept all publicly trusted WebPKI roots (all roots in the Google, Apple, and Mozilla root programs).

Peridot is our staging environment — it currently accepts testing roots, and we're happy to add more. We'd welcome monitors and CAs to test against it and share any feedback.

Aquamarine is our production log, which we intend to submit for inclusion in the approved log lists for Google and Apple following validation of Peridot. We are internally targeting 99.9% uptime.

We plan to submit both logs for inclusion once initial testing is complete. Please note that GoDaddy is already submitting all newly issued certificates to the production log (Aquamarine). Feedback is very welcome — feel free to reach out at ct...@godaddy.com or find us on the Transparency Dev Slack.

Best,

Lee Sautia

Hi Lee,

This is great news, love to see new CT operators and I am glad Sunlight is proving useful.

Could you share some details on the backend? Does it use the POSIX filesystem backend or the S3 one?

Is the home page (like https://tuscolo.sunlight.geomys.org/) reachable anywhere? I run a Prometheus scrape of all Sunlight log metrics, and it's moderately useful while developing, so I don't have to guess as to the performance observed by other operators.

Cheers,
Filippo
