Ticket Description: Scheduled router maintenance by Swisscom at CERN
Scheduled Starttime: Scheduled Endtime:

Problem Description:

Swisscom has told us that they will perform maintenance on their router at CERN on Sunday night (6 December 2300-2400 CET). Since we have another connection to Swisscom in Zurich, and two other transit connections (Global Crossing at CERN and TeliaSonera in Zurich), all traffic will be able to be rerouted.
