Ticket Description: Scheduled fiber replacement between Orbe and Bern (21.9.2021)
Scheduled Starttime: 2021-09-21 13:00:00Scheduled Endtime: 2021-09-21 17:00:00

Problem Description:

Part of our fiber link Geneva/CERN - Bern will be moved to the cable of a new provider. We expect an interruption of about 2 hours in the indicated maintenance window. No service impact is expected since alternative routes exist for all services.

Affected:

From 2021-09-21 10:27 until 2021-09-21 17:00
Impact: no more redundancy
Service: P2P/OPN
Sites: CERN-EQUINIX, L2VPN-RKAU-INDIANAPOLIS, L2VPN-RKAU-SANTACLARA, L2VPN-RMUE-INDIANAPOLIS, L2VPN-RMUE-SANTACLARA, SYNGENTA-INTERNET2, SYNGENTA-JANET

Actions:

The early interruption was caused by a mismatch in planning between two field teams. After resolving that, the maintenance proceeded successfully and we now see the links up and working stably for more than 24 hours over the new cable. This ticket will now be closed.

The old fiber has been interrupted already at 10:27, we are investigating why this has happened before the expected time. It may not be possible to re-establish the old fiber before the maintenance window. In this case the interruption is expected to be prolonged by a few hours.

2021-09-21 09:20
The switch over to the new fiber route has been shifted to the afternoon. Due to modified measuring procedures, the interruption will be longer than originally anticipated.
