Problem Description:

In order to prepare for the forthcoming upgrade of our optical transport system we need to move to a new in-house cable in Arth-Goldau.
This will interrupt all DWDM links between Lugano and Z├╝rich.
It will also interrupt the fibers used by HSLU to connect PHSZ. But we plan to interrupt the two fiber links one by one in order to keep network access all the time.
While all backbone traffic and all EoMPLS based OPNs are rerouted automatically to backup paths the OPN link CNAF-GRIDKA-LHCOPN-001 will be interrupted.
