`Thanks. I did see some explanation of why they're often near London. I'll see if I can find it again.

Maybe the much-vaunted Rolls-Royce mini nuclear power stations?

Like fusion which is always 30 years away, I suspect SMRs will always be 5 years in the future.

I saw someone BTL on the Guardian get very snotty with someone who said that re: fusion - "oh, are you an engineer in this field? Because I am." I waited for the "I am very intelligent", but it never came.

Laziness. They want to hop in a cab and show their config guys where the kit lives.

They will feed you some bullcrap about latency.
But all current cloud works on a 3 copies in geographically distinct sites basis.
Where Geographically distinct is set to match the exclusion zones of a nuclear incident.

If your application is sensitive to tenths of milliseconds latency, then Cloud isn't the answer you need.
A good example of this would be the national grid, who have premises housing computers relatively close to major sites.
Hint: There's a lot of national grid that's in NotLondon.

And if you're running cloud stuff that is millisecond sensitive....
You're asking for trouble fomr black hats who learned their tricks during the high-frequency trading boom.
