reported surprisingly normal Internet routing patterns from Japan following the mega-earthquake and tsunami. The vast majority of Japanese network prefixes in the global routing table stayed active. Renesys noted traffic patterns from Japan Internet Exchange, as well as secondary outages in several countries following cuts to the Pacific Crossing cable.
