I'd agree, it's super easy to think such errors won't happen had they just used a fairly safe language and sane architecture. Or unit test, race detectors, etc.

I'd agree, it's super easy to think such errors won't happen had they just used a fairly safe language and sane architecture. Or unit test, race detectors, etc. I suspect that few organizations that do all that, have a process/culture of ignoring bugs in the wild -- and those that do have such complicated domains that explaining the error is hard. Software best practices today would probably also involve sending metrics, logs, error reports, etc. That said, it's still extremely easy get embrace a culture were unexplainable errors are ignored. Especially in a cloud environment.
