Hi Paul,

The weekly dump of the planet.osm file happens Thrusday morning our time, finishing mid to late morning. That data is then loaded into a PostGIS database (more hours) from which the Mapnik renderings happens.

Tiles are only marked to be re-rendered when people actually look at them so when you first go to an area, you don't see any change. Some time later, depending on how many other tiles around the world are being view at the same time, your rendering will be done and when you go back, there are your changes.

For various technical reasons (disk space etc.), this process breaks and is re-run, so it can be well into the weekend or early next week before you see the changes from mapnik.

Check out te osmarender layers though. Osmarender is now running on a new server and it is turbo-charged. Changed tiles are marked automatically and can be re-rendered within the hour. Some times it takes longer though, or you can request a manual re-render which happens real fast.
