The Dead Server Still Gets Traffic

Medium

Problem

Paradox Shop serves 1,400 requests per second with four Medium application servers. Last night one backend failed, but the load balancer kept sending it requests until an operator removed it manually. Repair the existing design so failed backends are removed automatically and the remaining servers can serve all 1,000 RPS during the failure window.
