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.
