> Additionally because there are no people, we can take all the oxygen and most of the water vapour out of the atmosphere which reduces corrosion, which is a significant problem in data centres First time I hear corrosion is a problem in datacentres. I never noticed any corrosion on any machine at home or work. Does it have to do with the cooling of datacentres?

Maybe it is related to mitigation of sea water facilitated corrosion?

I think you may be thinking of something else. This was posted today, an hour ago, on the BBC.

Im pretty sure I heard about this a couple of years ago too

They did a mini-version in the US a few years ago, this one is 4x the size and 100x the compute

I think part of it is that even problems that are small/unnoticeable at the individual level become big when multiplied by a huge N.

For example, I don't think I've ever had a hard drive fail in ~30 years in computing, well without being dropped that is, yet look at the Backblaze reports:

Is there a benefit over just putting it in a boat/coastal building and using water (perhaps pumped from some depth) for cooling?

Boats in that part of the world are subject to severe stresses because of the weather. And boats are always moving, even in harbour. Just maintaining a reliable cable connection to a boat is more challenging than connecting to a subsea container. Placing the container on the sea floor avoids almost all of the weather related problems.

2016 article... but still cool! *edit, no its not, I have too many tabs open and mixed it up with the blog post listed in the comments. ignore me

Interesting idea but the maintenance must be painful. Let's say a hard disk fails, what do you do?

It's a fail-in-place data center. If a hard disk fails, you don't do anything. They used to replace telephony equipment all the time too, now it's just a locked room in a building. This is pushing data centers to be more hands-off.

So they don’t do anything? Eventually you’re just maintaining stacks of errored and broken computers.

Yeah. Fail in place over the service lifetime. When enough stuff is failed that it isn't worth keeping down there, you pull it up and refill it.

By then you've replaced the datacenter and you can shift the workload and then salvage it.

In theory you'd only leave it down there for three years anyway before everything in it is worth zero, at least to the IRS.
