Ticket Description: Scheduled Software Upgrade BA2, BE2, EL2, LS2, FR1, ZH2
Scheduled Starttime: Scheduled Endtime:

Problem Description:

*** The Software upgrade is postponed to Thursday, November 29 ***

We will upgrade the IOS software of our routers BA2, BE2, EL2, LS2, FR1 and ZH2.
Except for ZH2 / University of Zurich, all connected sites are redundant and internet traffic will automatically re-route through alternate paths.
The upgrades will be done between 0:00 and 7:30 on Thursday morning, November 29.
For each router the upgrade will take around 15 minutes.
University of Zurich and organisations behind it will lose internet connectivity during the upgrade of ZH2 as their connection is not redundant.
