With input from our community, we have decided to move out the turn-off date for new ACMEv1 registrations to November 8, 2019. As of November 8, all new accounts will need to be created via ACMEv2.
We’re going to use the original date of November 1, 2019 as another 1-day brownout period. We’ll disable new ACMEv1 registrations on November 1, then re-enable them on November 2 before finally turning them off altogether on November 8. Hopefully this will give a little more time to update any implementations that are lagging.
As a reminder, you can continue using your same ACMEv1 account ID for ACMEv2 and existing rate limit adjustments will still apply (assuming you have requested and received a rate limit adjustment).
We’ve updated our public Google calendar accordingly. Please subscribe to the API Announcements category for future updates.
