Box, one of the leading cloud-based storage, file-sharing and collaboration services providers, has expanded the physical reach of its data center network, adding nine “upload locations” in North America, South America, Europe, Australia and Asia.

The Los Altos, California-based company is making a major push to expand internationally, and strategically placing its patent-pending Box Accelerators in locations other than its primary data centers gives its international clients a lower latency when they upload their files. Box has three primary data centers: two in California and one in Las Vegas.

The Accelerator network currently only supports uploads, with plans to add download functionality in the future, Box CEO and co-founder Aaron Levie told All Things D.

“We've introduced an enterprise architecture that scales with the pace of today's business and addresses the explosive growth of content creation and sharing,” Levie said in a statement.

“As Box continues to expand internationally, it's critical that we provide all our customers with a consistently great experience and rapid data access. Box Accelerator provides the fastest, most secure channel to connect businesses with their content in the Cloud.”

Developed in-house, the Box Accelerator uses patent-pending routing technology that analyzes user traffic based on location, operating system and browser preferences of the user to optimize for fastest file-transfer speeds.

It also continually evaluates external factors that affect transfer speeds to determine the fastest data-upload path. Finally, the Accelerator ensures that all data is encrypted throughout transit.

Box commissioned an independent company Neustar to test the technology. Neustar reported file uploads at 7MB per second, according to Box.

Sony, Six Flags, American Hospital Association and Targus Group International became four of the first customers to use the Box Accelerator.
