There was a major power outage in Amsterdam on November 6th, which took
down the power at 2 major housing locations (Nikhef and SARA), which
house the original 2 AMS-IX sites, and lots of routers.
Even though Amsterdam (and AMS-IX) is a major hub for european
connections, most worked as usual, though some Dutch destinations has
higher than normal delay and packet loss.
