He use a geo-fenced AWS hosting environment.
All of our hosting is built on AWS (Amazon Web Services) and is geo-fenced to Australia. This means your data is securely stored in an Australian availability zone based in Sydney.
Recently AWS has added an new server facility in Melbourne where APP availability will also be based. This ensure redundancy and reduces the possibility of APP downtime.
