Affected Users of one of the many servers behind this switch

Two modules of an important switch in the main C&CZ server room lost power during the preparation of planned maintenance. This disconnected ca. 75% of the servers in the room from the network. Moving the modules to new PDU’s kimited the downtime to ca. 15 minutes.
