I’m surprised at the delay in impact detection: it took their internal health service more than five minutes to notice (or at least alert) that their main protocol’s traffic had abruptly dropped to around 10% of expected and was staying there. Without ever having been involved in monitoring at that kind of scale, I’d have pictured alarms firing for something that extreme within a minute. I’m curious for description of how and why that might be, and whether it’s reasonable or surprising to professionals in that space too.
