To help you test your apps on as many mobile devices and networks as possible, we have established our data centers in different locations across the globe. These data centers have now been merged into a single cloud. This allows you to access all the devices from all our data centers through a single platform. But with this comes a challenge, if you want to test your apps on devices located in different data centers that are thousands of miles away, then the app has to be uploaded to our secure cloud storage in each of the data centers. This is done to provide you a secure and smooth experience when you start-off with testing.
