When using a Storage Zone as your Pull Zone origin, you can configure a custom 404 page to display when requested files don't exist. ## Setup **1. Create the error folder** In the root of your storage zone, create a folder named `bunnycdn_errors`. **2. Upload your 404 page** Create a file named `404.html` with your custom HTML content and upload it to the `bunnycdn_errors` folder. To return an image instead, upload a file named `404.png` and remove any `404.html` file. **3. Verify** Navigate to a non-existent URL on your Pull Zone to confirm your custom 404 page appears. ## Folder structure ``` /your-storage-zone/ └── bunnycdn_errors/ └── 404.html ``` > [!NOTE] > > This feature only works when your Pull Zone origin is a Bunny Storage Zone. > For external origins, configure 404 handling on your origin server.
