|Ticket Description:||Fiber interruption between Bellinzona and Faido|
Problem Description:There is an interruption of the SBB fiber between Bellinzona and Faido.
SUPSI and USI is without redundancy. All traffic is rerouted over the backup path.
The cross border connection CNAF-GRIDKA-LHCOPN-001 is interrupted.
The reason of the fiber cut are rodents. In order to fix the cable, SBB had to install an extra splicing box in a tunnel. It explains the small attenuation increase we noticed. SBB plans to remove the splicing box (by replacing the complete cable segment) in early 2012.
Affected:From 2011-11-27 04:39 until 17:00
Impact: Total loss of connectivity
From 2011-11-27 04:39 until 17:00
Impact: no more redundancy
Service: network access
Sites: CSCS, HSLU, TI-EDU
The link is up again - all tests are successful.
We called SBB NMC and informed about the interruption and asked if the maintenance planed today in Erstfeld will be canceled.
We will be informed by SBB NMC as soon as there is more information available.
14:45 SBB NMC informs about unplanned work on the their cable between Bellinzona an Faido - which should not affect our cable.
