In 2016, Microsoft made plans to operate an experimental underwater server farm off the coast of Orkney. The nitrogen-atmosphere enclosed server farm was actually moved into position under the sea in May 2018, and included 855 servers. Powered exclusively by electricity from the Sun and wind, the server farm operated for two years, until May 2020, when the experiment ended, the enclosed tube was recovered, and brought to the surface for analysis. Preliminary results showed only 8 of the 855 servers failed during the two-year test, a failure rate of just 1/8 that of Microsoft's above ground server farms.
