> The power vulnerability for airports was never made more obvious and painful than in Atlanta seven years ago. An underground electrical system fire in late 2017 damaged two substations and caused a complete outage lasting nearly 12 hours at Hartsfield-Jackson International Airport

1. UK’s has one major airport to get out of the country—Heathrow. Gatwick and that lot don’t carry the same weight. When Heathrow goes down, you’re proper stuck. Atlanta has DC, Miami right there.
2. UK allows transit visas, so half the people transiting can’t even step out the terminal, what do they do when the airport is closed?
The US doesn’t allow that, everyone clears customs/passport control, so no ‘no man’s land’ limbo for stranded passengers.
3. Heathrow's outage is going to take 24 hours as of right now. That's twice Atlanta
"right there"
It is a ten hour drive from Atlanta to DC. It is a nine hour drive from Atlanta to Miami.
It is a six hour drive from Heathrow to Paris.
Most importantly, you're in the same country whereas in the case of LHR closing the number of airports able to handle widebody long haulers...are essentially all in countries with different customs and visas.
But Dublin airport has about 1/2 the gates of Heathrow...
From which airport? The one that is closed because there's no power?
2: I don't know if they've done it, but the UK can grant entry for a few days to affected passengers. This will be part of a contingency plan.
3: The airport reopened for some flights already.
Both Gatwick [0] and Stansted are busier than either Washington airport [1], and if you're considering Miami as an alternative to Atlanta then why not similarly ridiculous options like Paris, Amsterdam, Dublin for passengers stuck in Heathrow?
Miami and DC aren't even close to the nearest major airport cities to Atlanta. Charlotte and Orlando are many hours closer and busier [1] in terms of commercial passengers (though still not as convenient as the UK's comparable airports).
Only about a quarter of Heathrow passengers are transiting [2] and a significant portion of those are citizens of the US, EU, UK and other countries who don't need a visa. Maybe 10% of passengers are stuck in limbo, not half of them.

I’ve been using Edinburgh airport and Glasgow airport for 40 years to “get out of the country”.

Anchorage International Airport, amongst few (less than a handful really) other US airports, have separate international section with sterilised transit.
To be fair, I'd probably be more interested to hear what major airports are doing to avoid a reoccurance of CrowdStrike-type scenarios. Which is perhaps a more likely re-occurence than loss of substation feeds.
