Coastline processing on openstreetmapdata.com is stuck for more than a 
month now, mostly because a lot of back and forth with tagging of large 
lakes as coastline.

For information: to avoid major disruptions of map rendering due to data 
errors the coastline is not updated if there are larger changes in the 
geometry compared to the last time it was successfully processed.  Any 
addition or removal of a lake with coastline tag will require manual 
intervention and we do not have the time to manually check the data 
every day because some mapper somewhere wants to scratch an itch and 
decides to tag a lake outline with natural=coastline.
