Ticket Description: Scheduled Router reboot swiCHU1
Scheduled Starttime: 2017-09-08 06:00:00Scheduled Endtime: 2017-09-08 06:30:00

Problem Description:

Due to a memory leak and thus exhausting available memory we need to reboot our router swiCHU1.
This will be done between 6:00 and 6:30 as it seems to be the least traffic affecting from traffic graphs.
Internet Traffic for CHUV will be automatically re-routed via backup paths (swiCHU2).
There should be no impact for internet access.
Unfortunately, OPN access to HESSO-HESAV will be interrupted during the reboot as there is no backup.

The duration of the interruption is estimated at around 30 minutes.
