Problem Description:

At UZH Irchel - UPC will move the local loop fiber to an other cable.
No interruption of any service is expected - there is always redundancy.
All traffic will be rerouted automatically.
A second fiber link - used by UZH for their site at Kilchberg - will be interrupted too.

Impact: no more redundancy

The link is up and running.
In our announcement of this maintenance we forgot to mention that
SWITCH-CLOUD had no redundancy anymore and that we lost peering with Google and SwissIX.
Peering with Swisscom in Zurich was interrupted too - but the backup in Geneva automatically took over.
We apologize for ignoring this.
