# Limits and Quotas - CDN

## Limits

The current service iteration has the following limitations:

- The source content must be hosted on the Exoscale SOS service.
- Using a vanity domain for the CDN endpoint is not supported.
- The CDN cache cannot be explicitly purged - other strategies must be used to manage the cache lifecycle.
- Buckets with dots in their names cannot be served through the CDN.



## Quotas

| Usage | Quota |
| -------------------------------------------------------- | ------------------------ |
