Cloud computing relies on high-speed connections, and when you're moving large chunks of data around the higher the speed the better. So it's no surprise that Microsoft has been investing in undersea cabling to connect its Auzre data centres around the world.

Microsoft's investments include cable links from North America to Ireland and the UK, and from the United States to Asia via the New Cross Pacific (NCP) cable. NCP will connect a site in Oregon to Chongming, Nanhui and Lingang on the China mainland, as well as South Korea, Taiwan and Japan.
Absent from that list are the Australian data centres in Sydney and Melbourne which Microsoft launched last year. That's not entirely surprising though -- customers using the Australian centres are relying on geo-redundancy between the two cities and don't necessarily want their data to go offshore.
