35 Conclusions RAL & PIC need backups!!! CNAF needs a 3 rd route into CERN Reroute 2 Amsterdam-CERN lambdas via Lyon Reroute USLHCNET (FNAL-CERN) via Lyon SARA-NDGF should be routed on northern leg of NORDUnet’s “Southern Cross” (for Cop-Ham part) –via Padborg, Kolding, Odense Further investigations required in particular concerning: –Physical routing of GRIDKA-IN2P3 in Paris area –Leased lambdas passing through London
