Ticket Description: Scheduled software upgrade swiLI1 and swiLI2
Scheduled Starttime: 2017-04-11 19:00:00Scheduled Endtime: 2017-04-11 21:00:00

Problem Description:

Due to security and bug fixes we will upgrade the software of our routers swiLI1 and swiLI2 on Tuesday, April 11th between 19:00 and 21:00.
No outage for Internet access of UNILI, LLV or HTWCHUR is expected because we will install the new software sequentially so that always a backup path is available.
However redundancy is obviously reduced during the downtime of the router when upgrading.
The duration of the upgrade is estimated at around 20 to 30 minutes per device.
