This paper proposes a method to measure a specific aspect of a system's robustness - the handling of maintenance events. Past research in the area of robustness benchmarking has focused exclusively on injecting a realistic faultload into a system and examining the system's robustness against the set of injected faults. However, faults are not the only events that can cause a system outage. Maintenance events, such as the replacement of a failed hardware component or the installation of a software patch, may also result in a system outage. In this paper, we describe a benchmark for measuring a system's robustness against a class of hardware maintenance events.
