Ticket Description: Scheduled software upgrade swiCR1, swiCR2
Scheduled Starttime: 2017-04-03 19:00:00Scheduled Endtime: 2017-04-03 21:00:00

Problem Description:

Due to security and bug fixes we will upgrade the software of our routers swiCR1 and swiCR2 on Monday, April 3rd between 19:00 and 21:00.
No outage for Internet access of HTW Chur, UNILI or LLV is expected because we will install the new software sequentially so that always a backup path is available.
However, the non-redundant OPN link NTB-HTWCHUR from Buchs to Chur will be interrupted during the upgrade procedure.
The duration of interruption is estimated at around 20 to 30 minutes per device.

* Maintenance has been postponed from Friday, March 30th, to Monday, April 3rd, 19:00 - 21:00.
