-The DNS for letsencrypt.example.com should point to all IPs e.g.
-  letsencrypt.example.com 86400 A 10.10.10.10
-  letsencrypt.example.com 86400 A 10.10.10.20
-</WRAP>
 Now when fetching the certificates for example.com, LE should follow the redirect to letsencrypt.example.com.
 Then you can setup something like rsync to copy the certs from the primary server to other servers if there is something like DNS load balancing.
