Was this incident really recorded minute by minute or is that made up? I've noticed a lot of companies that give this kind of detail like to give a minute by minute report, I just don't understand how they get that accuracy?
If you're working in Slack or chat, you've got a minimum of half a dozen people typing and putting out suggestions and offering to investigate something. That's all time stamped. And even if you're not doing that real-time, you may be using something like a GitHub issue to discuss the problem via comments, which are also time-stamped.
No one at the moment of the incident is probably going "Ah, it's 8:01, better write down that I identified the problem." It's most likely "hay I think I got it one sec" and then that works. Or doesn't. But hopefully it does.
judging from the number of 'sorry's in the text, seems like post mortems have been slowly adapted into a very specialized form of semi-fictional stage drama in which the audience is pandered to excessively through the use of hyperbolic apology.
