&gt; HTTP-01 verification works quite well behind load balancers - it&#x27;s a simple GET request to a specific URL.<p>Running the client on one of the servers frequently results in it hitting one of the other servers in the cluster. It&#x27;s a pain in the ass - you either rely on luck and retry a number of times until it hits the right server, or you have to go the more manual route and deploy the challenge directory to all of the servers.<p>DNS doesn&#x27;t care how many servers there are, as long as there&#x27;s the right record in place.
