#cloud latency

Frontend reliability is often discussed in terms of outages. Teams prepare for failed API calls, downtime and visible crashes because those failures are easy to recognize and measure. However, in many modern applications, the bigger challenge is not complete failure but latency. Systems rarely go fully offline. Instead, they become slow enough that users lose confidence in the interface long before anything technically breaks. Most frontend engineers have experienced this in production. A page eventually loads, but only after several seconds of waiting. A save action succeeds in the backend, yet the interface remains unchanged long enough that the user clicks the button again. A dashboard renders immediately, but the critical data appears so late that the application feels unstable. In practice, users rarely distinguish between “slow” and “broken.” If an interaction feels uncertain or delayed, trust drops quickly. As frontend systems become increasingly dependent on distributed cloud i
