-                Let's Encrypt offers, right now, four such URLs. Two for
-                the own legacy version of the ACME protocol, commonly named ACMEv1.
-                And two for the RFC 8555 version, named ACMEv2.
+                If you configure more than one URL, each one is tried in a round-robin
+                fashion after a number of failures. You can configure how quickly or
+                delayed that happens via the <code class="directive">MDRetryDelay</code> and
+                <code class="directive">MDRetryFailover</code> directives. The default setting
+                makes a failover after about half a day of trying.
             </p><p>
-                Each version has 2 endpoints, as their is a production endpoint and a
-                "staging" endpoint for testing. The testing endpoint works the same, but will
-                not give you certificates recognized by browsers. However, it also has
-                very relaxed rate limits. This allows testing of the service repeatedly
-                without you blocking yourself.
+                All other settings apply to each of these URLs. It is therefore
+                not possible to have two with different
+                <code class="directive">MDExternalAccountBinding</code>s, for example.
+            </p><p>
+                For testing, CAs commonly offer a second service URL.
+                The 'test' service does not give certificates valid in a browser,
+                but are more relaxed in regard to rate limits.
+                This allows for verfication of your own setup before switching
+                to the production service URL.
