|Ticket Description:||Interruption on the fiber route Villigen - Regensdorf - Zürich|
Problem Description:There is a problem on the fiber route Villigen - Regensdorf - Zürich. We lost our services between PSI-West and Zürich-ZHDK, as well as local access to FFHS in Regensdorf.
*** current situation: all services up using special temporary settings in order to compensate the fiber disorder ***
Affected:From 2021-06-17 15:14 until 2021-06-18 08:18
Impact: Total loss of connectivity
more analysis has been done to understand the unannounced cable modifications of June 17. To properly fix the problem, splicing work in a big fiber joint is needed which requires a maintenance window. In the meantime, SWITCH has improved its temporary workaround - it is now redundant.
the fiber provider is planning to fix the problem tomorrow June 23
fiber provider is on the way to Regensdorf for troubleshooting
The fiber provider cannot enter the building today, but plans to do so on Monday morning.
photos taken on-site this morning show the presence of a new fiber panel which indeed carries our fiber links
fiber provider will investigate whether any manipulations were made on-site
access to FFHS restored by temporary changing configurations of links to Villigen and Zürich [for yet unknown reasons, the fiber pairs from east and west have been swapped]
SWITCHlan service between PSI-West and Zürich restored; FFHS remains inaccessible, however
fiber route Villigen - Regensdorf - Zürich interrupted
All times are in local Swiss time CET / CEST.
