In my book, operating software is a different skill set from writing software. In the 911 outage, my first thought was: Alright, we have a server accepting calls, and dispatching calls. If there is too much of a difference between incoming and dispatched calls, there is a problem. Maybe it's a capacity problem and we don't have enough 911 operators, maybe it's a software problem, maybe we're dealing with a DoS. I don't need to know or understand anything about the dispatch software, and I'm pretty sure I can monitor, measure and alert these metrics independently from the software. We can twist, turn, push and shuffle Dev, Ops and DevOps around, but good operators largely try to mitigate failure and risk, including their own limited imagination how much infrastructure and software could fail at once. That's a very different skill than trying to make a single component in a network bug-free.
