All three outages were related to technical glitches of one sort or another. And on top of that, the Chinese stock market tanked. That wasn’t a technical fault, but it didn’t stop people from lumping it together with the other three big news events of the day, adding in some horrendous commutes in New York and San Francisco and saying the sky is falling. Or, maybe, don’t panic: These are all unrelated events, and coincidences happen. Then again, maybe we should panic: These are symptoms of how badly software sucks, and it’s only going to get worse. It’s tempting to join the chorus of extremist headlines, but I think it’s more productive to try to draw some useful lessons from the day.
