Ticket Description: Scheduled fiber maintenance in Cossonay (22.7.2020)
Scheduled Starttime: 2020-07-22 00:05:00Scheduled Endtime: 2020-07-22 05:00:00

Problem Description:

GAS&COM has scheduled a maintenance on their fiber cable in Cossonay on July 22, 2020. Our link Cern - Fribourg will be interrupted, but our services will continue to work over alternative paths.

There is another maintenance in the same area during that night, but we could coordinate the downtimes with the involved providers in order to avoid a major loss of redundancy in our core backbone.

Affected:

From 2020-07-22 00:05 until 2020-07-22 05:00
Impact: no more redundancy
Service: P2P/OPN
Sites: RKAU-INDIANAPOLIS, RKAU-SANTACLARA
