N2 - Low Earth Orbit (LEO) satellite networks are increasingly deployed, yet users continue to experience frequent, short-lived outages. We present Roman-HitchHiking, a system for measuring LEO satellite outages globally and in near-real time. Roman-HitchHiking significantly reduces the measurement overhead by leveraging path redundancy to eliminate duplicate probes to shared pre-satellite routers, thereby reducing overall network traffic and increasing coverage. With Roman-HitchHiking, we identify large clusters of simultaneous outages across geographically diverse regions, pointing to potential centralized failures that traditional outage detection systems overlook. Roman-HitchHiking is open-sourced to enable reproducibility and foster further research on LEO outages.
