End of Life Plan for ACMEv1

In preparation for the production turn down of ACME v1 we are planning to disable new ACME v1 registrations in the staging environment during the following dates of this year.

  • August 6th to August 7th

  • August 13th to August 15th

  • August 27th to Sept 3rd

We will be permanently disabling new ACME v1 registrations in the staging environment on October 1st.

As a reminder in November we will disabling ACME v1 registrations in the production environment as well. Please use these progressively longer staging brown-outs to verify that your organization will not be affected by the start of the production ACME v1 end of life in November. We will announce similar brown-out dates for production in the near future.

We’ve made a public Google calendar with these dates and other scheduled ACME API events that may be helpful to others.

Thanks!

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.

In preparation for the full shut-off of the ACMEv1 API in June 2021, we will have occasional ACMEv1 issuance and renewal brown-outs each month. The schedule below outlines our plan and our API announcements calendar is updated accordingly.

We previously indicated that these brown-outs would be once a month and not more than 24 hours in length. We feel that schedule won't alert the greatest number of subscribers who use ACMEv1 so we have planned several brown-outs each month of increasing length covering various times of month and days of week. As stated in the original announcement, the intention is to induce client errors that encourage subscribers to update to clients or configurations that use ACMEv2.

Please use these progressively longer brown-outs to verify that your organization will not be affected when we entirely disable ACMEv1 as a viable way to get a Let's Encrypt Certificate.

We have disabled the ACMEv1 API in Staging and Production in line with our ACMEv1 deprecation plans. This brownout will last aproximately 6 hours.

Will update our status page maintenance window and this thread when the brownout is completed.

Please note, this brownout includes the Staging ACMEv1 API. We realized this endpoint was not listed in our original plans and have decided that Staging brownouts will occur in line with production until the end of March when we will fully disable ACMEv1 in Staging. The previous post has been updated with this information.

Edit:
I mistakenly wrote in the status.io update that the next maintenance would be 2021-03-15, but that was incorrect. I've cleaned my glasses off and confirmed that my eyes are working again.
