When was the planetfile rerendered the last time? The latest release of openstreetmap-carto was 16 days ago, but I don’t see any changes on the largescale tiles yet.
On 25/26 April some rendering of z9-z12 started (Munin), but it seems to be interrupted.
Does nobody know the answer?
You may be better off to try get an answer on the OSM IRC http://wiki.openstreetmap.org/wiki/IRC
https://webchat.oftc.net/ to channel #osm
The new style-release has not been deployed to the OSM servers yet, see https://github.com/openstreetmap/chef/issues/120
Therefore, the last rendering of tiles in zoomlevel <= 12 was on the previous release, so around beginning of February.
