hesela.devMetastable failure
A metastable failure is a persistently degraded system state sustained by feedback after its initiating disturbance has ended.
Separate the trigger from the mechanism maintaining low useful throughput; the absence of a new hardware fault does not establish recovery. [1]
The OSDI 2022 cache experiment used a one-hour recovery observation window, not proof of permanent non-recovery. Its incident study is not a population failure-rate estimate. [2]
