Maintenance on production servers this weekend Nov 12 and 14

We are planning a maintenance on our production servers this weekend from Friday November 12 at 18h00 CET till Sunday 14 at noon.
We will minimize the impact on the site but online prices will be unavailable from time to the time. It will stay possible to send us your offline price requests. We”re so sorry about this interruption to i.materialise but we”re working on making it better.
