Problem Description:

Due to security and bug fixes we will upgrade the software of swiIBM2 on Wednesday evening, April 5th, between 19:00 and 21:00.
Internet Access to IBM Lab will be interrupted for about 20 to 30 minutes during the maintenance window.
All other organisations in the ring IX1-IBM2-WSL1-WSL2 will have a reduction of redundancy since the fiber path via IBM2 will not be available during the downtime. However, traffic will be re-routed via backup paths.
