# Traffic Allowances for the Salesforce CDN

Each byte of traffic that’s requested, whether it’s an image or a complex report, counts toward your content delivery network’s (CDN) usage amount. The amount of traffic allowed over a CDN depends on the license that you purchase. Understand how to monitor your Salesforce CDN usage and what happens if you exceed the terabyte limit.

### Required Editions

Within each production environment, you can define multiple domains in a sandbox, but only one custom domain associated with a sandbox org can use the Salesforce CDN.

## Traffic Allowances by License Type

If you have any of these items, you’re entitled to 48 terabytes of traffic per year and 10 single certificate domains.

- Salesforce CMS, Commerce Apps, or External Apps
- A Customer Community license, a Customer Community Plus license, or a Partner Community license

If you require more traffic for your org, contact your account representative to purchase additional terabytes. If you exceed the traffic allowance, a representative contacts you to discuss purchasing more terabytes for your business needs. To request more single certificate domains, you can log a ticket with Salesforce Customer Support.

Note If you exceed the traffic limit, we don’t shut down your site or move remove your domain from our CDN.

## CDN Usage Reports

You can use two reports to check your Salesforce CDN usage. A CDN Usage report is part of the Experience Management Package found in AppExchange. You can also create a custom report type with Domains as the primary object.

If you need help with managing your usage, contact Salesforce Customer Support.
