Large-scale Internet services are the newest and arguably the most commercially important class of systems requiring 24x7 availability. As a result, very little information has been published about their causes of failure. In an attempt to address this deficiency, we have analyzed detailed failure reports from three large-scale Internet services. Our goals are to (1) identify the major factors contributing to user-visible failures, (2) evaluate the (potential) effectiveness of various techniques for preventing and mitigating service failure, and (3) build a fault model for service-level dependability and recovery benchmarks. Our initial results indicate that operator error and network problems are the leading contributors to user-visible failures, that failures in custom-written front-end software are significant, and that online testing and more thoroughly exposing and handling component failures would reduce failure rates in at least one service.
