At a previous job, I worked with two guys who were excellent in a crisis. One of them used to run operations, the other was a crusty old programmer who’d been around for a while. I tried to learn as much as I could from both of them.

At around the same time, I was watching HBO’s The Wire. One scene had a high-profile shooting with a frantic police response; people were running everywhere trying to help. The lead commander on the scene gave this instruction to his sergeant: “Slow this thing down to a crawl. Give these bastards no chance to fuck up in a meaningful way.”

And then it hit me. That’s exactly how they ran the calls. I asked them about this, and they said absolutely – human nature, when things are broken badly, is biased towards action. You want to try to make a change, to reboot a system, to do something to hopefully make things better. But often if you were not careful, you risk losing information about the outage you are in. Best case scenario you luck into fixing the problem and don’t know how. Worst case? You’ve changed the state of an already broken system, and have done nothing but add more variables to unwind.

So now, every time I’m on an outage call, I try to do what Wes and Tim and Major Rawls would all do: I take control, pump the brakes, and make sure that we are capturing enough information about the current state that we don’t confuse ourselves further.
