Bug in the Let's Encrypt certificate authority code

"Let's Encrypt were in the news a few days ago when they announced they
had issued a billion certificates. Yesterday they broke the news that
they're forced to revoke 2.6% of active Let’s Encrypt TLS/SSL
certificates due to the 2020.02.29 CAA Rechecking Bug. They're in the
process of notifying some users that their certificates will be revoked
today, March 4th 2020. Check the thread for more details and to see if
you're affected."
