Cascading failure is a typical failure mode in distributed systems: when a component responds slowly due to excessive load or an anomaly, upstream services keep retrying or piling up requests, thereby transmitting pressure to other dependent components and ultimately causing large-scale unavailability.

UnverifiedIn large-scale distributed systems, after the first failure causes nodes to go offline, the remaining nodes bear higher traffic, and if redundancy capacity is insufficient, a second round of failures may be triggered — known as a Cascading Failure.79% similarUnverifiedIn distributed systems, fault-tolerance mechanisms themselves can sometimes become amplifiers of fault propagation.78% similarUnverified级联失效的根本原因通常在于服务间的强耦合与缺乏熔断机制，上游服务响应超时会导致下游线程池被阻塞请求耗尽77% similarUnverifiedWithout exponential backoff, a brief server-side outage causes all failed clients to immediately retry simultaneously, forming a retry storm that is more destructive than the original traffic.75% similarUnverifiedThe unreliability of each link in the chain amplifies rather than cancels out, which in reliability engineering is known as series system failure.75% similar
