Ticket Description:	Scheduled interruption SBB-Fiber Oerlikon - Winterthur
Scheduled Starttime:		Scheduled Endtime:

Problem Description:

2009-06-28 20:00 - 2009-06-28 22:00
SBB moves the fibers of the links UZH - UniSG and ETHZ - ZHAW between Oerlikon and Winterthur to new cables. The East ring of SWITCHlan will be opened for a few minutes. This leaves some sites without redundancy. But no loss of connectivity is expected - all traffic will be rerouted automatically.

At the same time the dark fiber connection between UZH and ZHAW operated by ZHAW will be interrupted too.

Affected:

From 2009-06-28 20:00 until 2009-06-28 22:00
Impact: no more redundancy
Sites/Services: FHSG, HLI, HSR, HTW, NTB, PHTG, SLF, UNISG, ZHAW

Actions:

2009-06-28 20:20
All fibers has been successfully moved. The links are up and running again.

2009-06-25 13:57
The announced maintenance work didn't take place today.
It is deferred to Sunday, 2009-06-28
