# Update a CDN Distribution

IONOS CLOUD CDN: update properties and routing rules of a CDN distribution using the DCD

Once a CDN distribution is successfully created, the distribution is listed on the **Distribution overview** page

To update the CDN distribution details, follow these steps:

1\. In the **DCD**, go to **Menu** > **Network Services** > **CDN**.

2\. In the **Distribution overview**, select the CDN distribution to update.

3\. In the **Details & Edit CDN distribution**, update the distribution details needed:

* **Properties:** Refers to the **Domain** and **SSL certificate** details of the distribution. To update these details, see [<mark style="color:blue;">Define distribution properties</mark>](/cloud/network-services/cdn/dcd-how-tos/create-cdn-distribution.md#define-distribution-properties).
* **Edit routing rule:** This rule defines the rules for routing content requests to this CDN distribution. To update these details, see [<mark style="color:blue;">Define routing rules</mark>](/cloud/network-services/cdn/dcd-how-tos/create-cdn-distribution.md#define-routing-rules).
* **Delete routing rule:** Use this option to delete an existing routing rule.
* **Add routing rule:** You can create a routing rule. To do so, follow the steps in [<mark style="color:blue;">Define routing rules</mark>](/cloud/network-services/cdn/dcd-how-tos/create-cdn-distribution.md#define-routing-rules).
* You can drag and drop the routing rules to change the precedence of the rules to apply to the CDN distribution.

4\. Click **Save** to update the CDN distribution details with the changes made.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.ionos.com/cloud/network-services/cdn/dcd-how-tos/update-cdn-distribution.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `build a script that syncs our docs to a CMS` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
