In my direct experience, this isn't true if you're running something even vaguely mission-critical for your customers. Your customer's workers just know that they can't do their job for the day, and your customer's management just knows that the solution they shepherded through their organization is failing.
If akamai went down i have a feeling you'd see a whole lot more real life chaos.
if you run anything even remotely mission critical, not having a plan B which is executable and of which you are in control (and a plan C) will make you look completely incompetent.
There are very, very few events which some people who run mission critical systems accept as force majeur. Most of those are of the scale "national emergency" or worse.
And why should anyone be surprised? It's been about 80 years since "The buck stops here."[0] had any real relevance. And more's the pity.
