Revoking certain certificates on March 4th – 5th, 2020 UTC

Due to a bug related to CAA checking in Let’s Encrypt, millions of certificates will be revoked “today”.

To quickly check if your domains are affected, use this tool: https://checkhost.unboundtest.com/

If your domain is affected, you have to renew your certificates right away.

As of 2020-03-04 00:45 UTC we have not started revocations. We are gathering some data on how long it will take to revoke before we offer an estimated start time. The BR mandated deadline of 5 days to revoke by is 2020-03-05 03:00 UTC and we plan to finish revocations by that time.
