Now the finger pointing. It appears there were failures on the National Grid side, but Heathrow can't outsource their resilience and wash their hands of it.

You need to plan, build for, and test your resilience. You can't run CNI that falls over with the loss of one feed.

Likely errors all round that then lined up and boom.

@FloatingOnion oh, no, this is just straight up typical corporate-grade idiocy. For example, Heathrow did plan for a failure like this.
Their plan basically said they would have 12-24 hours to restore services. In other words, they intentionally planned to fail. Because they didn't want to spend money.

@rootwyrm Risk accepting no resilience because you can't separate impact and likelihood or don't believe it will happen to you isn't unusual.

It's a choice. Not what I'd consider a resilience plan by any stretch, or the choice I'd make, but then I don't get to make those choices.

Until people get past the costs or are forced to pay by regulations then poor choices are likely to continue.

@rootwyrm I'm not even going to try and fit a rant about risk acceptance into a toot.
