How Let's Encrypt Runs CT Logs

Earlier today we released a blog post about how the SRE team operates our Oak and Testflume CT logs. If you have any questions about the architecture or design choices, feel free to ask!

To give an update on timing, the Oak log shards will soon be usable by other CA’s in Google Chrome version 78 and Apple’s Safari browser. Google has also published a read-only mirror of our Oak log shards for use by auditors and researchers. :tada:

We look forward to contributing to better transparency in Web security!
