Ticket Description: Scheduled Redundancy Upgrade PoP WSL
Scheduled Starttime: Scheduled Endtime:

Problem Description:

This afternoon (Monday, August 4th) between 13:30 and 17:00 our PoP WSL in Birmensdorf will be converted to a redundant router setup.
During the upgrade procedure Internet connectivity of WSL might be interrupted for several minutes.
Backbone connectivity between swiWSL2 and IBM2, as well as swiWSL2 and EZ2 will be interrupted for some time as well. Thus, the IBM PoP in Rüschlikon will lose redundancy in that time period.
