The server hosting the scenemodels database and web frontend at https://scenery.flightgear.org/ will go down temporarily and for short periods of time over the next couple of days.
I don't expect outages to last longer than up to an hour. The entire process should be complete by the end of February 2017.
Background: I am changing the mainboard and the drive array. More CPU cores, more RAM and a 2TB SSD RAID to get ready for the ever growing database and worldwide osm2city data.
