Ticket Description: Scheduled maintenance in Chur
Scheduled Starttime: 2016-03-02 09:00:00Scheduled Endtime: 2016-03-02 16:00:00

Problem Description:

We will replace the 1G router swiCR2 located at HTW Chur by two new 10G devices
Around noon we will move all network connections from the old to the new router.
This will interrupt the network access of HTW Chur and also interrupt the P2P link between Buchs and Chur for about 5 minutes.
In the context of this upgrade we will also make some OTDR measurements and interrupt the link between Chur and Vaduz for a few minutes.
For these measurements there will be no interruption at all - all services will be rerouted to backup links.

The network access of HTW Chur and the P2P link between Buchs and Chur were interrupted for a few seconds only.

We try to migrate the the network access of HTW Chur today between 18:00 and 19:00.
If it works we will migrate the P2P link between Buchs and Chur too.

The migration of the network access of HTW Chur from the old router to the new one didn't work. We switched back to the old configuration for the moment.
