The database import has finished and the rendering daemon is running again.
The Openstreetmap and German Carto stiles have been updated to their most recent releases, so rendererd maps should finally look the same as on openstreetmap.org and .de again. The rest of the styles will follow today.
Database updates still need some work, so for now map data is of last Thursday, the time of the last full planet export.
Do you have any style with house numbers?
Sorry for the late reply,
the default CartoOSM style, and a few others, do render house numbers, but only at high zoom levels.
