On July 19, what was supposed to be a harmless software upgrade brought down a huge chunk of the health care, banking, flight, and travel systems.
While my dinky little practice wasn’t affected, several of my patients were in other ways. Tests that had to be rescheduled, flights canceled ... inconveniences, but not life altering.
Things are allegedly fixed (at least until next time) but there may be fallout down the road. People who had delayed medical procedures could have a different prognosis depending on what the results showed when they were done. Hopefully this won’t happen.

But it’s a reminder of how vulnerable our whole world is to disruption of the internet, not to mention the power grid and software systems. Paper is time consuming, and takes up a lot of space, but as long as you have a decent pen and enough light to read it you’re fine.
I’m not saying we should go back to paper. It’s more expensive in the long run, takes up shelf and closet space, kills trees, has to be shredded after a time, and turns yellow around the edges. It also makes it a pain to copy and transfer records. With paper I wouldn’t be able to take all my charts with me to refer to when I leave town on a busman’s holiday. The benefits of digital far outstrip paper or we wouldn’t have switched in the first place.
But it’s still kind of scary to realize how much we depend on software to keep things running smoothly. The events of July 19 were unintentional. Someone looking to cause real trouble could do worse — and there are plenty out there who would love to — and we’re putting our faith in companies like CrowdStrike to protect us from them.
But, on the flip side, we’re asking others to do the same. We often use the phrase “trust me, I’m a doctor,” in jest, but the point is there. People come to us because we have knowledge and training they don’t, and they’re hoping we can help them. We spent a lot of time getting to the point where we can hang up a sign that says so. And we, like everyone else, are not infallible.
We’re individuals, not machines. Both are fallible, though in different ways. In CrowdStrike’s case the machines didn’t fail, they just did what the humans told them to do. Which didn’t work.
The bottom line is that even the most well-meaning will make mistakes.
But it’s still pretty scary because, even unintentionally, there will be a next time. And between now and then our world will become even more dependent on these systems. None of us want to go back to the preconnected era, it’s too much a part of our daily lives.
Like the long list of potential side effects on any drug we prescribe, it’s a trade-off that we’ve accepted. And at this point we aren’t going back.
