[Solved] Maintenance of Zoom at 8 PM on March 12, 16 and 19

Due to the spread of the Coronavirus, our supplier, Nordu.net, needs to prepare for a possible increased need for the service.
They need to restructure in their computer room to quickly expand capacity if the need arises.

The work starts at the following times (exact finish time cannot be specified but they work on until they are ready in the evening / night):

Thursday, March 12, 8 p.m. 
Monday, March 16, 8 p.m.
Thursday, March 19, 8 p.m. 

This means that there may be malfunctions in Zoom during work. Unfortunately, this is done with short notice, but they hope that we understand the need for such work and that it is necessary to ensure continuous operation.
