+Confirm that there is not a total outage of the service. If not, the severity is
+likely low. Check for the request count and general network activity. If
+abnormally high, refer to the [traffic analysis run book][traffic_runbook] to
+identify and block any malicious traffic. If not, then check for a recent
+deployment that may have introduced a problem, and [rollback][rollback_docs] to
+the previous version if necessary.
