The access to Geant (the network backbone for Research and Education sites in Europe) is not available because of a routing issue in our provider network (SWITCH).
Most of the CERN traffic to Europe is going via the U.S.A.
SWITCH seems to have solved the problem and the traffic is again back in Europe.
