Site/line:     Géant STM-16 Primary

Problem Description:
The Geant link to Frankfurt has failed.

Problem Effects:
All traffic has rerouted over the backup link with possible loss of
performance.  Loss of resilience.

Problem History:
20080205 12:59 BN Geant Service Desk are chasing this up with the provider.
 There is no time-to-fix at present.

20080205 17:33 BN A number of routing issues to .si have been noticed that
may well be due to this issue.

20080206 08:03 BN Link came back up at 18:28.  As yet we have no RFO from
Geant.  The routing issue to .si resolved in or around the same time. 
Both of these will continue to be investigated.

20080207 10:05 BN Further link problems have emerged that are causing
increased latency towards Geant, but not actual link failure.  These are
being investigated by the GN2 service desk.

20080207 11:36 BN While all of the physical links appear to be working as
expected, asymmetrical routing has been detected, which may reduce
performance.  These issues have been raised with the Geant service desk.

Time to Fix:
6 hours
