There is a cache of tiles which is used when the rendering can not keep
up. The weekly planet import is running at the moment and I have
temporarily turned of the re-rendering of tiles so you will only seeing
tiles from the cache right now.

I'm in the middle of making some updates to the server to migrate the
cached tiles and rendering database to an external disk array which will
speed things up quite a bit. All the old tiles should still be
available, but the live rendering probably won't restart until some time
tomorrow.

If you really must see an image which has not been rendered, the export
tab should still produce an image for you.
