A study of end-to-end web access failures

We present a study of end-to-end web access failures in the Internet. Part of our characterization of failures is based on directly observable end-to-end information. We also present novel analyses that reveal aspects of end-to-end failures that would be hard to discern otherwise. First, we combine endto-end failure observations across a large number of clients to classify failures as server-related or client-related. Second, we correlate failures attributed to a client or server with BGP churn for the corresponding IP address prefix(es), to shed light on the end-to-end impact of BGP instability. Our study is based on failure observations during a monthlong experiment involving 134 client hosts (across PlanetLab, commercial dialup and broadband ISPs, and a corporate network) repeatedly accessing 80 websites. We find that
