This discussion focuses on hardware, software and operational failure modes. Collecting some critical metrics at one second intervals, with a total observability latency of ten seconds or less matches the human attention span much better. Try to measure your mean time to respond (MTTR) for incidents.

Meanwhile, on Android, the #2 and #3 sources of web traffic do not respect browser choice. This reduces friction and commensurately increases "engagement" metrics. [6]. On Android today and early iOS versions, WebViews allow embedders to observe and modify all network traffic (regardless of encryption).

For web-page loading, this slow-start approach can also affect metrics such as the first contentful paint, because only a small amount of data (tens of to a few hundred KB) can be transferred in the first few round trips. Many network interface controllers (NICs) even have built-in hardware-offload features for TCP.
