China launches commercial underwater data centre with 2,000 servers off Shanghai
China has officially commissioned the Lingang underwater data centre off the coast of Shanghai, deploying around 2,000 servers housed in pressure-resistant, seawater-cooled modules. The 24MW facility, valued at approximately Rs 2,000 crore, is powered entirely by an offshore wind farm. It boasts a power usage effectiveness (PUE) rating below 1.15 and consumes no freshwater, making it notably energy-efficient. The project draws on learnings from Microsoft's Project Natick, which submerged 855 servers off Scotland's Orkney Islands in 2018 and reported significantly lower hardware failure rates than land-based counterparts. Unlike Natick, which was eventually discontinued, China's facility is now in full commercial operation.
