At around 12:40 there was a lot of water in the XHQ 2nd. floor. It comes from the roof, snow melting.

Called TN here at the gate, and they will take care for the moment about it.

Update 13:50:  TN brought three buckets and a warning sign. While I meet the cleaning lady and she dried everything up and placed another bucket ot the Leckstelle nr. 4.
