…I know it can be slow, but 18 days seems a bit excessive (osmarender has updated) “Noname” hasn’t.

Something amis?

That could happen sometimes by gravitation waves and solar winds. If you’re not posting any details like node- or wayids or permalinks the reason could be anything. Just a guess: Clear you browser cache.

(there’s an additional note now added to the second one) Nothing earth shattering, just some name corrections.

I’m perfectly used to it taking a few days - but 18 seemed excessive, so was wondering if there was a general problem.

Personally, I blame the Icelandic volcano. Or maybe misplaced sarcasm.

I guess you just changed the name of these ways. Correct? If you only alter tag-values, Mapnik won’t rerender the tiles until a complete database reimport is done. If you moved a node or the whole way Mapnik will rerender the tiles.

(no, that doesn’t mean you should move a node to force a rerender; append “/dirty” to the URL of the tile.)

Exactly. Sorry, I forgot to mention the dirty-Flag.
Open the PNG-Image out of the map (right click → show image). In the address-bar append “/dirty” to the URL, so it looks like this example:

http://c.tile.openstreetmap.org/10/538/369.png/dirty

This will force Mapnik to update this tile (and all other zoomlevels?)

7

No, not other zoom levels. It will rerender the tile and usually some adjacent ones (depending on the zoom).

Thanks chaps. That flag is handy to know.
