Justification of the work: We regret to inform you of an maintenance we have to perform on our Fiber network on site ISZ „blaues Haus“ Burghausen. We will upgrade several older 1G Infrastructure to 10G. During this work our technicians will replace several Fiber Switches. The maintenance should be completed during the first 0,5 hours, but a 1 hour maintenance window has been quoted to cover all eventualities. Back-out plan: 30 minutes are reserved to revert any changes, should we experience any unforeseen issues during the works.
