Yeah, perhaps not as elegantly worded as I would have hoped, but there are many reasons things "go down". Just one of those elements is the internet part, there's also transport, power, and other elements that combine to make this complex system called the internet. If you N+N or N+1 your power, perhaps something similar for your connectivity is important. Or you just plan to be down/broken periodically for 30 minutes and have a plan to cover that.
Agreed.
The building where our NOC is located sometimes gets evacuated. Having a plan for that is important. During one visit, there was a small fire in the building (or so we were told). Certainly an unexpected event that disrupted us for ~30 minutes.
And, if it is important to you, you will have N+N NOC's - ie, more than one, and different buildings, cities, or countries, depending on your requirement.
The handling and response of these events certainly is important. I do want to understand why and how it's so bad so if there are things as a SP in the community we can improve upon we can do that.
I suspect, as I touched previously, the most noise will come from the people who are the least realistic, and least prepared. Personally, I live with the expectation that whatever it is (power, fiber, transport, ISP, highways, fuel delivery, etc.) will at some point be broken, degraded, or otherwise unavailable, and you have to plan accordingly. Personally (and I speak for NAC) I/we don't care, really, if any upstream IP provider breaks; we have made appropriate plans to work around that in an automated fashion. Hope that answers your more general question.
