+The [=remote end steps=] are:
+
+1. If no Bounce Tracking Mitigation Service is currently running, return a [=error|WebDriver error=] with
+    [=error code=] [=unsupported operation=].
+
+1. If the [=stateful bounce tracking map=] contains a malformed host, return a [=error|WebDriver error=] with
+    [=error code=] [=unknown error=].
+
+1. Let |list| be a new list of the [=site=] [=hosts=] in the [=stateful bounce tracking map=].
+
+1. Let |temp| be [=bounce tracking grace period=].
+
+1. Set [=bounce tracking grace period=] to 0 seconds.
+
+1. Run the [=bounce tracking timer=] algorithm.
+
+1. Set [=bounce tracking grace period=] to |temp|.
+
+1. Return [=success=] with data |list|.
