This is a difference in what you are buying. When you are buying a dedicated server, there isn't exactly a good way to hide that the thing has just gone up in smokes. When you buy a storage API, sure, failure rates go up, latency increases 100x, but after a few hours its probably back to normal. Of course, with the increased abstraction, you get more problems. "Availability zones" are useless when most cloud outages…

If you're in with the big cloud providers you have no choice. Hybrid cloud is economically impossible due to the bandwidth costs. Yet somehow, at smaller providers and dedicated hosters bandwidth is usually included as a too-cheap-to-meter feature. Gotta love cloud innovation.

Bandwidth is cheap until you run out and then it's very expensive.

A single lead-acid battery is putting out such a tiny amount of hydrogen. Put it in any room. It's a big fat nothing in a fire too: https://www.youtube.com/watch?v=ndfe0c00gwo Something could short but shorts are possible and dangerous even if no batteries are involved. Or get a LiFePo battery and put it in a metal tub.

That looks like enough fire that spreading to my wooden floors or desks, carpets or skirting boards seems more likely than not?

It burns about as well as any random piece of electronics in a plastic shell. Any of those could spread too. If you want a battery that's less flammable everything else in the room I guess you're out of luck, but I don't think that's a reasonable standard.

Isn't hydrogen produced only while the battery is charging, or at worst, when discharging? If so, this still makes them much safer as they're otherwise inert while not in operation, compared to lithium-polymer which contains materials flammable at all times.

LiPo and LFP are very different things. LiPo is probably the biggest fire risk battery chemistry in common use today. LFP is pretty safe. LTO even more so.

Yes, I am aware of other "L" batteries that are safer. I was just commenting about how lead-acid is still relatively inert compared to the "fiery" kind of L batteries.
