# Dedicated Load Balancer Updates

> For the full documentation index, see: https://docs.mulesoft.com/llms.txt

The CloudHub dedicated load-balancer service provides quarterly updates that include the latest OS
and security patches. If necessary, additional patches provide updates more often. These updates
don’t include feature changes.

Because these updates contain required security patches, you can’t roll back these updates once
applied.

When updates are available, an **Update** button appears on the load balancers page:

The **Update** button also appears on the details page for the individual load balancer:

## Update the Dedicated Load Balancer

The **Update** button indicates a load balancer requires an update. You can schedule the update to
occur at your convenience. Before updating the Production DLBs, update the Sandbox DLB and run
required tests.

To update a load balancer:

1.  From Anypoint Platform, click **Runtime Manager**.

2.  Click **Load Balancers**.

3.  Click the **Update** button.

4.  At the **Update load balancer** prompt, click **Update**.

    Click the **View release notes** link for details on the update.

    > [!IMPORTANT] When you update a DLB with static IP addresses, the update might require
    > additional static IPs. If you’re prompted to add these new IP addresses to your allowlist, do
    > so before you click **Update**.

The update results in a rolling restart with no downtime. Some in-flight requests might experience a
brief interruption during the restart. No transactions are dropped or lost provided that transaction
times are shorter than 600 seconds or the configured Mule Application Response Timeout, whichever is
smaller.

If you experience a sustained outage after updating, contact MuleSoft Support.
