Problem Description:

Our fiber provider ewz has announced a maintenance window for replacing UNC sleeves on a cable. They will need to cut and re-splice fibers. This will interrupt the SWITCH connection from Uniklinik Balgrist to the Toni-Areal. However, this link is the backup connection, so no customer impact is expected. During the maintenance window there will be no redundancy for up to 8 hours.


From 2021-10-09 21:00 until 2021-10-10 07:00
Impact: no more redundancy
Service: network access
Sites: UKB

The fiber maintenance has concluded, attenuation levels are nominal, and the link has been observed to be stable. Closing this ticket.

All times are in local Swiss time CET / CEST.
