Google Cloud Downtime Postmortem
> One of the features contained a bug which would cause the GFE to restart; this bug had not been detected in either of testing and initial rollout.I wish they elaborated more on what type of bug was that, which  was not caught by testing / initial rollout. Either tests must be poorly written or the bug must be very subtle.On an unrelated note: kudos to Google for publishing this postmortem and hope that this becomes an industrywide practice. I also wish they publish (a belated) one about Google+ and their throng of messaging apps over the years.
