China has put 2,000 servers in sea near Shanghai, taking off from a Microsoft project that shutdown in 2020, where the company sank 855 servers in North Sea

China has switched on a commercial underwater data centre off the coast of Shanghai, dropping roughly 2,000 servers onto the seabed in the Lingang Special Area and wiring them directly into an offshore wind farm. The facility runs at 24MW, sits 10 metres below the surface and more than 10km out, and uses the surrounding seawater in place of chillers and cooling towers. It took 1.6 billion yuan of investment, roughly Rs 2,100 crore, and is a joint effort between HiCloud Technology and state-owned China Communications Construction. Commercial operations began in May, after trials in February and construction wrapping up last October.

The design it borrows from belongs to Microsoft.
