Problem Description:

We will perform maintenance on one of our core fiber spans on the axis Geneva-Berne-Basel-Zürich tomorrow, some fibers will be switched to newer ones from a different provider, for other spans we need to optimize the working range of our amplifiers. This will lead to multiple short interruptions of the span.

For data traffic there are alternative paths available at all times.

The stable frequency transfer Berne-Basel-Zürich will experience multiple short disruptions.


From 2021-10-07 10:00 until 2021-10-08 16:00
Impact: no more redundancy
