Ticket Description: Scheduled emergency fiber maintenance between Zurich and Zurich Airport
Scheduled Starttime: 2016-06-11 00:30:00Scheduled Endtime: 2016-06-11 05:00:00

Problem Description:

Tomorrow, our fiber provider needs to carry out an emergency cable replacement. The cable has been partly destroyed due to a fire earlier this week. This maintenance will leave MeteoSchweiz with reduced redundancy. There will still be left two geographically redundant fiber paths but one of the routers at Zurich airport will become a SPOF.


From 2016-06-11 01:07 until 2016-06-11 04:16
Impact: no more redundancy
Service: network access

The links are up and successfully tested.
The power level of the lasers are back to normal - span loss didn't change significantly.

Our fiber provider informed us that they needed to postpone this emergency maintenance due to operational constraints. The work will be carried out next night (see scheduled times above).
