About the CT Announcements category

This category is a low-volume announcement list for the Let’s Encrypt certificate transparency logs. Watch this category if you submit certificates to one of our logs, or otherwise want to stay up to date with changes to our certificate transparency environment.

To receive email notifications of announcements, sign up for a forum account and use the ‘Watch’ feature (circle in upper right of the category page). If you’d prefer not to create an account on this forum, you can also subscribe to the RSS feed, or use an RSS-to-email service like IFTTT or BlogTrottr to get updates.

If you want to hear about outages and maintenances that will affect the CT logs, check out our status.io page, which also lets you subscribe. There are separate components for the ACME API environments and our distinct CT logs.

Only Let’s Encrypt staff can post to this category. If you’d like to post follow-up questions, please start a new thread in the Issuance Tech category, or any other appropriate category.
