Google's Liquid Cooling

Your linked articles are about immersion cooling, which is "liquid cooling," I suppose, but a very different thing. Do OVH actually use immersion cooling in production? This seems like a "labs" product that hasn't been fully baked yet.

OVH _do_ definitely use traditional water-loop/water-block liquid cooling like Google are presenting, described here: https://blog.ovhcloud.com/understanding-ovhclouds-data-centr... and visually in https://www.youtube.com/watch?v=RFzirpvTiOo , but while it looks very similar architecturally their setup seems almost comically inefficient compared to Google's according to their PUE disclosures.

Based on how their data centers burn down, they don't even use liquid in their fire suppression systems.
