Ticket Description: Scheduled interruption of SBB fiber at Geneva railway station
Scheduled Starttime: 2011-12-14 20:00:00Scheduled Endtime: 2011-12-14 23:59:00

Problem Description:

There will be a maintenance by SBB on the two fiber links “EPFL – CERN” and “EPFL – UniGE” (14.12.2011, 20:00 – 23:59). We expect an interruption of less than one minute.
This will reduce the redundancy of the UniGE network access.


From 2011-12-14 20:03 until 2011-12-14 20:04
Impact: no more redundancy
Service: network access
Sites: UNIGE

The fiber cable has been swapped with an interruption of 20 seconds only. All links are up and running normally. We notice a slight increase of attenuation, which was expected however.
