Problem Description:

2006-08-06 00:23
The links
are interrupted.
There is reduced redundancy for all sites of Eastring but no loss of connectivity.
All traffic is rerouted automatically.
The same event caused an interruption of a fiber pair rented by ZHWin/PHZH/PHSH for their own network.

The fibers rented by PHZH and ZHWin for their own network are fixed too.

SBB expects to fix the problem by late afternoon. Either by putting a temorary cable at the same route or by using fibers in an existing cable at an alternative route - which might be about 7 km longer.

ZHWin informed that the links Winterthur - Wädenswil and PH Schaffhausen - PH Zürich are interrupted too.

SWITCH called SBB Netop and got the information about a fiber cut in Kempthal. A car crashed into a SBB building which caused severe damage to the fiber infrastructure.
