That does not say it took 19 minutes for alerts to appear. Following could mean any amount of time.
It's 19 minutes until active engagement by staff. And planned rolling restarts can trigger alerts if you don't set thresholds of time instead of just thresholds of count.
It would be nice though if alert systems made it easy to wire up CD to turn down sensitivity during observed actions. Sort of like how the immune system turns down a bit while you're eating.
10 minutes to alert, to avoid flapping false positives. 10 minute response window for first responders. Or, 5 minute window before failing over to backup alerts, and 4 minutes to wake up, have coffee, and open the appropriate windows.
I'd like to think that a company the size of Microsoft can afford to have incident response teams in enough time zones to cover basic operations without relying on night shifts.
That’s some very carefully chosen phrasing.
I think if you really wanted to do on call right to avoid gaps you’d want no more than 6 hours on primary per day per shift, and you want six, not four, shifts per day. So you’re only alone for four hours in the middle of your shift and have plenty of time to hand off.
