"my cluster is unresponsive" is not straightforward at all. in fact it's the vaguest, most un-straightforward kind of problem you could have.

one of the interview questions i ask is "a customer calls in and said their system is unresponsive. what do you do?"

this will weed out a bullshitter 99% of the time, because the potential problem domain is the entire OSI stack, across the open internet, and also could be potentially on the customer side, which is most likely also a complex setup.

if you want someone who can actually fix the problem to help you, it's going to cost a lot of money. one of these people is six figures. now imagine a whole team of them, 3 shifts a day, every single day, forever.
