Chapter 1 was an interesting case study about a very expensive bug. Have you ever had to resolve an incident like that? Or does some other type of difficult or expensive defect come to mind?
One of the hairiest defects I’ve had to troubleshoot was probably an issue I worked on that manifested as a “socket hang up” error in a Node.js application and seemed to be caused by the Kubernetes API server sending a TCP FIN packet before it received any application data. We still haven’t gotten to the bottom of it despite many packet captures and back and forth with the cloud provider’s support team.
One of my most expensive “bugs” was when I ran up a big cloud bill at my previous company. I actually can’t remember what the bill was for, but it was solved by correcting the issue and then calling AWS and pleading with them to reverse the charges.
