Ticket Description: Scheduled software upgrade swiIX1
Scheduled Starttime: 2017-04-04 19:00:00Scheduled Endtime: 2017-04-04 21:00:00

Problem Description:

Due to security and bug fixes we will upgrade the software of our router swiIX1 on Tuesday evening between 19:00 and 21:00.
This will affect lopvi, ix-nfg1, SWITCH-SCION-edge-1 and Community DNS transport to SwissIX, which will all be unavailable during the upgrade.
Expect time of outage is between 20 and 30 minutes during the maintenance window.
Other organisations connected to the IX1-IBM2-WSL1-WSL2 ring will have reduced redundancy since the fiber path via IX1 will be unavailable during the downtime. Traffic is automatically re-routed to the remaining path.
