Ticket Description: Scheduled interruption of SBB fiber in Zurich ZBLZ
Scheduled Starttime: Scheduled Endtime:

Problem Description:

2009-10-26 00:30 - 04:00
Due to maintenance work SBB will interrupt the fiber Basel-Zürich near ZBLZ in Zürich. This will affect our link BA1-ZH2 and thus the redundancy of our sites connected in Basel.
However no impact is expected - all traffic is automatically rerouted using the backup link.


From 2009-10-26 00:30 until 2009-10-26 04:00
Impact: no more redundancy
Sites/Services: ETHZ, UNIBAS

Testing done and confirmed to SBB: attenuation remains unchanged, link works error-free. Ticket closed.
