- **Billing**: Pay-per-use model based strictly on egress traffic; free ingress transfers.

## Log Storage

The values below come from the STACKIT documentation and update themselves.

> From the STACKIT docs: [CDN features and options › Built-in log storage](https://docs.stackit.cloud/products/network/load-balancing-and-content-delivery/cdn/basics/features-cdn/#built-in-log-storage) (Source updated 14.09.2026, copied 05.10.2026)

By default, STACKIT CDN stores the 10.000 most recent log entries from the past hour. You can query these logs directly via the API to perform quick troubleshooting or traffic analysis. A log entry contains the following information:

| Field | Description |
| --- | --- |
| Status | The HTTP status code returned to the client (e.g., 200, 404). |
| Timestamp | The exact date and time (UTC) the request was processed. |
| Remote country | The ISO 3166-1 alpha-2 country code where the request originated. |
| Cache | Indicates if the request was a HIT (served from cache) or a MISS (fetched from origin). |
| Size | The total volume of data transferred in the response, measured in bytes. |
| Data center | The identifier of the specific CDN edge location that handled the request. A list of data centers is available [here](https://docs.stackit.cloud/products/network/load-balancing-and-content-delivery/cdn/reference/points-of-presence/). |
| Path | The URL path of the requested resource. |
