Always follow the CDC's advices...
Zombie Preparedness | CDC
I know it sound like a joke, but it's an fun exercise in preparedness; if you can prepare for a zombie attack, you will be prepared for pretty much any situation.
I'd rather be phishing!

How do they intend to handle zombie deniers?
Or the one who claims you won't become a zombie if you eat enough vitamin C and Zink?
Or that zombies are created by the Chinese government? (Ok, there might be some truth in that one.  )

I added a "Kill Zombies" feature to some of my code last year.
It's helped.

Burning electronics as a server power supply goes to the land of the dead. Great smell on a Sunday morning.
Proved an old theory I had heard. Electronic devices run on smoke. If the smoke escapes, they stop working.
Now, for extra credit, what is the probability that the remaining PSU functions until the replacement arrives?
If you can keep your head while those about you are losing theirs, perhaps you don't understand the situation.

In any redundant system of mode N, where N is the number of failures which can be tolerated and maintain primary function, the number of typical failures will always be at least N + k where k > 0.
Proof is left as an exercise for the student. Professional experience will be accepted in lieu of formal proof.

Murphy's law indicates the probability is closer to 1.0.

I have a feeling "Murphy's Law" originated with Ogg, inventor of both the wheel and the buy-4-get-1-free discount. Not to be confused with Okk, who was far in advance of his time as the first dental hygienist.

The bit I hate about dead PSU's is the kit they take down with it ... I've had HDD's start to behave badly and die, RAM go bad, even processors give up the ghost. I suspect that when some PSU's die they put huge spikes down the power outputs and gently fry the equipment at the other end.
We used to call that smell "going analog" as th analog design section would always smell like that ... 
I remember them working on a battery fast charger and running out of the building with a string of soldered together batteries that was still glowing red hot - and trailing that smell behind them!

No, kittens are usually made by cats.
(we don't do pets of any sort)
(we did try kids, discovered that you can't return them)
(grand kids are fun though)

Mainly because you can return them.

I've heard it described as short-term leasing. I don't have grandkids but I do have grandpuppies, and there is a definite rental amount you pay while they're visiting. The same amount of spoiling and over-indulgence goes on. One good thing in my case is that the dog park is free, as opposed to our local amusement park which under normal circumstances runs about $50 a person per day.

Parents do look at me rather oddly when they show me the new kids and I ask if they kept the receipt ...

Jesus - I had a battery explode on me once - one of the old ones you could top up - I made a mess of connecting jump leads - sparks everywhere and then BANG - my boiler suit resembled a string vest. I was very lucky not to get injured.

I was round at a mates house enjoying a bevvie or two many years ago, when his phone rang. It was a gentleman known as "Ston" with a motorcycle problem:
"'Ere Chris, I heard you are good with bike electrics?"
"Might be, Ston. What's the problem?"
"My batteries aren't charging"
"Batteries? How many have you got?"
"The one the bike came with, a 6V I knicked off a moped, and a car battery strapped to the seat."
"Royston, I know nothing about bike electrics."
To be fair, the car battery was inside a plastic carrier bag after the first one ate through his jeans under braking ...
Strange man, Ston ... he ended up marrying his lawyer because it was cheaper than her fees ...

WTF did he have a car battery strapped to the seat ?

A) The bike battery was dying and had difficulty turning over the engine.
B) He wouldn't steal a battery from a fellow biker.
And
C) It was too big to fit where the bike battery was.
There is a twisted logic in there, somewhere.
This may also help you to understand why marrying his lawyer was a good idea ...

that almost makes sense, except what did she get out of it? 
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, weighing all things in the balance of reason?
Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?

The probability of the spare PSU functioning is e-CN·t, where CN is the critical need level, and t is time from the failure of the primary PSU.

Cheers for redundancy at least!  Hopefully no downstream components were affected.
This reminds me that I need to start planning for a replacement home/office server. The current one is nearing the 9 year mark. The only h/w upgrade through that time has been a larger SSD for the system drive (first one was a 64GB) and a switch to SSDs for the data drives after a spinner failed around 5 years ago. That was the last system that I actually assembled.

Quote: Cheers for redundancy at least
Hear! Hear! Not only redundancy of hardware, but having an image of the systems drive OS around. And of course backups of the data - But I'm sure you're well set up in this regard! If you buy a brand new machine for your server - consider one with a NVMe M.2 SSD for the systems drive. They're about the same price as SATA SSDs, but much faster as they plug directly into the PCI bus. My apologies if I am preaching to the choir!
