Problem Description:

The SWITCH's PoP at Cern, Geneva has to be moved in a new rack row. Our routers swiCE2 and swiCE3 and our servers will be individually switched off and relocated. The maintenance window starts 15.7.2008 at 12:00 until 16.7.2008 at 15:00. Major services and important links are expected to operate, but with reduced or no redundancy. Following circuits are at risk:
- GEANT 2 IP primary and backup access for SWITCH and Cern
- SWITCH Global Crossing Global Transit
- Skyguide backup IP access
- Backbone links Lausanne-Cern, Lugano-Cern

The Sorrento DWDM equipment is not affected by these migration.
Please ignore any alarms from PoP Cern during the maintenance window.
