Where are VWO data centers located?

Our Content Delivery Network (CDN) runs on IBM Softlayer; and the servers are spread across 10 locations—Japan, Australia, Singapore, Netherlands, London, Paris, France, Germany, and 3 cities in the US to help us serve dynamic requests for tests. However, all the Test data is stored centrally in Washington DC and Research data is stored in Dallas, United States. We may update our data center geography and server locations based on customer requirements or to meet security compliance requirements.
