Problem Description:

On May 20, 2015 there was a fiber break between UniL and IMD related to a gas explosion on a construction site next to the fiber cable (see Ticket 20150520_1). This is the announcement for the final repair of the cable.

IMD and HEP-VD will lose redundancy. There's no impact for EPFL and UniL regarding SWITCHlan services. However, EPFL and UniL might use fibers on the cable for their internal network redundancy.
