Finally, it is clear from our website performance monitoring that despite the performance improvements from our improved web-code, network latency effects will always reduce performance for users far from our servers. As a result we have been investing in mirror sites in parallel, to improve performance for users and provide redundancy. We have recently deployed a mirror site in China in collaboration with the Beijing Genomics Institute, Shenzhen (BGI-SZ). This site's primary service region is our users in and around China as the connections between the UK and China are relatively slow. We will shortly be deploying a full mirror to the US west coast and have also been investigating operating servers in commercially managed cloud compute facilities.
