Of course, how else would I know the exact failure times, my service monitoring only polls every few minutes. That doesn't help me with my knowing how my service is performing though, I'm not offering a ping service. More importantly, I do know I had an error loading twitter at Thu 11 Nov 04:17:01 GMT 2021, however my websites (and google and hackernews) were working. At 17:53:01 GMT Twitter took over 2 seconds to load it's first http page, far beyond the normal 400ms. Google took 23 seconds to load this morning, BBC News just 0.071. On the other hand I also need to provide services which can't cope with outages measured in milliseconds. Good luck with complaining to a cloud provider that your traffic vanished for 4 seconds. Those services thus have multiple connections on independent hardware and circuits with no single point of failure
