= Configuring route timeouts

You can configure the default timeouts for an existing route when you
have services in need of a low timeout, which is required for Service Level
Availability (SLA) purposes, or a high timeout, for cases with a slow
back end.

[IMPORTANT]
====
If you configured a user-managed external load balancer in front of your {product-title} cluster, ensure that the timeout value for the user-managed external load balancer is higher than the timeout value for the route service. This configuration prevents network congestion issues over the network that your cluster uses.
====

.Prerequisites

* You need a deployed Ingress Controller on a running cluster.

.Procedure

. Using the `oc annotate` command, add the timeout to the route:
+
[source,terminal]
----
$ oc annotate route <route_name> \
--overwrite haproxy.router.openshift.io/timeout=<timeout><time_unit> <1>
----
<1> Supported time units are microseconds (us), milliseconds (ms), seconds (s),
minutes (m), hours (h), or days (d).
