Ticket Description: Scheduled router migration in Geneva
Scheduled Starttime: 2020-03-31 08:00:00Scheduled Endtime: 2020-03-31 09:00:00

Problem Description:

SWITCH has installed a new router @UniGE. Meanwhile, it is integrated in our 100G core backbone and we plan to migrate all links on Tuesday 31.3.2020, between 08:00 and 09:00. This work was planned as a regular update, but has been accelerated due to the recent traffic surge.

For most services, the maintenance is expected to be smooth, without any interruption, thanks to redundant links. However, point2point OPN links passing through swiGE2 will be subject to a short interruption of <30s.


From 2020-03-31 08:00 until 2020-03-31 09:00
Impact: no more redundancy
Service: P2P/OPN
