Ticket Description: Fiber cut in Lugano

Problem Description:

We have lost the northbound links (to Zurich/Arth-Goldau) from Lugano. Presumably this is due to a fiber cut. Connectivity of Lugano and surroundings is still guaranteed through westbound connections (towards Bern, Sion/Lausanne, Geneva).
