 Consecutive Gateway Failure
 ^^^^^^^^^^^^^^^^^^^^^^^^^^^
 
-This detection type takes into account a subset of 5xx errors, called "gateway errors" (502, 503 or 504 status code)
-and is supported only by the :ref:`http router <config_http_filters_router>`.
+In the default mode (:ref:`outlier_detection.split_external_local_origin_errors<envoy_v3_api_field_config.cluster.v3.OutlierDetection.split_external_local_origin_errors>` is *false*) this detection type takes into account a subset of 5xx errors, called "gateway errors" (502, 503 or 504 status code) and local origin failures, such as timeout, TCP reset etc.

 If an upstream host returns some number of consecutive "gateway errors" (502, 503 or 504 status
 code), it will be ejected.
