Hi,

This post is informational:

Lets Encrypt discovered a bug in their CA software (boulder) related to CAA
checking code. They have decided to revoke a subset of certificates issued on
March 4, 2020.

More information:
https://arstechnica.com/information-technology/2020/03/lets-encrypt-revoking-https-certs-due-to-certificate-authority-bug/

If you are using letsencrypt certificate(s) as I am, here is a way to check
whether you are affected -

curl -d 'fqdn=example.com' https://unboundtest.com/caaproblem/checkhost

* replace "example.com" with your own domain(s).

Found the helpful command from the comments on slashdot about this issue.

Kind regards,
Didar

Thanks for passing that along,  Didar.  It shows my cert is OK as well.
