Updated on February 1, 2024


Vultr Object Storage provides a secure, scalable, and cost-effective solution for seamless data management and retrieval, making it a go-to choice for developers and businesses of all sizes. You can combine object storage buckets with Vultr CDN to cache all objects globally to improve the availability and reduce latency.

This article explains how to use Vultr CDN to enable Global Caching for Object Storage. You will set up a new bucket to store static files and deliver the files using your Vultr CDN URL instead of the object storage URL.


Before you begin:

  9. Copy the generated Vultr CDN URL to use for accessing your accelerated objects.


  1. Access your Vultr CDN endpoint using a web browser such as Firefox.
  2. Verify that an XML Access Denied prompt displays in your web browser to represent the root bucket directory.

  3. Append your Vultr CDN URL with a valid image file available in the bucket. For example image1.png.
  4. Verify that the file displays correctly in your web browser.

  5. Append your Vultr CDN URL with a non-viewable, but downloadable file available in the bucket. For example,

    Download a sample file from the Vultr CDN URL

  6. Verify that the file auto-downloads to your computer. Open your web browser downloads page and verify that the download source URL points to your Vultr CDN endpoint.


You have enabled global caching for object storage using Vultr CDN. Depending on the objects available in your target object storage bucket, you can cache the static assets to multiple locations around the world depending on your Vultr CDN configuration.
