Introducing Static CT Log: Rennet and Gouda

[Pim van Pelt]

Hoi colleagues,

I’m excited to announce the first of two Static Certificate Transparency logs, operated by IPng Networks in Switzerland. We reviewed the extensive public documentation from Sunlight and want to give some appreciation to Filippo et al for sharing the Tuscolo setup.

Our Sunlight logs:

• A staging log called [Rennet], incepted 2025-07-28, starting from temporal shard rennet2025h2.
• A production log called [Gouda], incepted 2025-07-30, starting from temporal shard gouda2025h2.

Rennet is a test log using 'testing' ccadbroots, and we cordially invite operators to test it. Andrew, Luke and Joe, thanks in advance for taking a look!
Gouda is to be our production log, which we will be submitting for inclusion in the approved log lists for Google and Apple after initial testing and validation of Rennet.

Rennet and Gouda are hosted on a Dell R630 hypervisor with ZFS on SAS3 storage, at NTT in Rümlang (near Zürich) Switzerland. They are running Sunlight v0.5.1. 
We've allocated 16GB of ECC memory and 12 vCPU to the virtual machine to start with. We've put our VMs in a private network, front-ended by a set of NGINX servers across Europe. You can reach us at <ct-...@ipng.ch> and the Transparency Dev slack.

Lastly, we are working on a TesseraCT static log, for which we're expecting hardware delivery in the upcoming weeks.

groet,
Pim, Jeroen and Antonis
