I was just reading and article in The Economist that Microsoft recently completed a years long test of locating a dozen server racks under the sea off the Orkney Islands.
The underwater data center suffered just 1/8 of the equipment failures of a land-based data center.
According to the article, some other possible advantages to locating data servers underwater:
1. Cooling is a big expense on land.
2. Land in cities like New York or London are expensive, but not the nearby sea floors.
3. More than 1/2 the world's population lives within 120 miles of the sea.
