Hi,

I read about LetsEncrypt revoking a bunch of security certificates earlier and wondered if I was going to be impacted? Is there anything I need to do to mitigate if so?

> \[Update 2020-03-05: The most up-to-date summary is at 2020.02.29 CAA Rechecking Bug\] Due to the 2020.02.29 CAA Rechecking Bug, we unfortunately need to revoke many Let’s Encrypt TLS/SSL certificates. We’re e-mailing affected subscribers for whom...

Many thanks in advance,

> Hi folks! We are aware of Let’s Encrypt’s [announcement this morning](https://community.letsencrypt.org/t/2020-02-29-caa-rechecking-bug/114591) regarding urgently revoking many of their issued certificates, and that this may cause concern for some of you. We totally understand those concerns. Our team is already launched into the work to renew all affected certificates that we automatically created for your sites. There were about 6,000 affected certificates, and our team has already begun renewing all of those certificates and the work should be complete by 0000 UTC…
