Working with Objects and Bucket FAQs

PhoenixNAP Object Storage Service supports objects up to 5 TB in size.


If you are uploading through the Management Console, you can upload objects up to 5 GB in size.

Bucket names are restricted to the following:

  • Only lower case alphabet (a-z), numbers (0-9), dashes (-), underscores (_), and periods (.) are allowed.
  • Bucket names must be unique. If you select a bucket name that has been taken already, you will receive an error message.
  • Bucket names must be between 3 and 63 characters long.
  • Must begin with a letter or number.
  • Must not end with a period or dash.
  • Must not contain two adjacent periods. (e.g. “example..bucket”)
  • Must not contain dashes next to periods. (e.g. “example-.bucket” and “example.-bucket”)
  • Must not be in the form of an IPv4 address. (e.g. “”)

Certain characters are forbidden in object names (folder and file names) and using them will return a 400 Bad Request response.

Unsupported characters are:

0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x0A (“\n”), 0x0B, 0x0C, 0x0D (“\r”), 0x0E, 0x0F, 0x10, 0x11, 0x12, 0x13, 0x14, 0x15, 0x16, 0x17, 0x18, 0x19, 0x1A, 0x1B, 0x1C, 0x1D, 0x1E, 0x1F


  • 0xBF (inverted question mark) at the end of an object name
  • 0x09 (“\t”) at the beginning of an object name is unsupported.

Other examples of unsuitable character sequences that result in 400 Bad Request:


The public can access objects through a web browser. Enable Public URL access and (optionally) notify people via email.
The web address that you retrieve will look something like this:


Another option would be to integrate a content delivery network (such as Amazon CloudFront) and use it to distribute content.

Data is stored in a robust flat-file structure where all objects exist at the same level; there are no subdirectories. The physical location of your stored data is at our datacenters in Phoenix, Arizona and Ashburn, Virginia, while Amsterdam, Netherlands is a virtual deployment location for phoenixNAP’s Object Storage Service.

Yes. When creating a bucket, choose among the three (3) available regions via the admin interface.

Buckets cannot be moved from one region to another. As an alternative, we propose creating a new bucket in the target region and transferring objects to that bucket.

Once an object has been created, its name cannot be modified. Instead, you can copy an object, rename the newly created object and delete the old one.

You are not able to do this. A bucket cannot change its owner (Group).

Access to data is controlled through the Management Console or API interface. You can set overall bucket permissions that will apply to all objects in the bucket, or you can set permissions for individual objects.
