Justification of the work: We regret to inform you of an maintenance we have to perform on our network on site 52-BCB „Business Center Burghausen“. We will rebuild a networking cabinet and replace the whole power supply and distribution. This will ensure stability and higher independence from the power grid. The maintenance should be completed in 3-4 hours, but a 9 hour maintenance window has been quoted to cover all eventualities. Back-out plan: 3 hours are reserved to revert any changes, should we experience any unforeseen issues during the works.
