One of those nebulous things is, I believe, whether any nodes were changed. Adding or changing street names amounts to simply changing the tagging of a way, whereas adding a completely new feature (or moving, or changing the shape of an existing feature) almost certainly involves changing the position or even existence of some nodes. In my experience, changes to nodes will quickly come to the attention of the tileserver, and rendered promptly. If nodes are left untouched, on the other hand, changes to way tagging can go unnoticed by the tileserver for days. I haven't yet determined whether changing the tagging on a node will get the tileserver's attention, or if node creation/deletion/moving is required. For that matter, I don't know if creating a way using entirely existing nodes will trigger a rerender, though I doubt it; changes to relations probably don't trigger an immediate rerender. Also, the far-out zooms (0 through 10 I think) can go multiple weeks between updates. Zoom 11 tiles seem to update on a shorter turnaround, but still not as fast as 12 and closer. (Zoom 11 tiles used to be as slow as 0 through 10, but that seemed to change shortly after a not-entirely-informed complaint I made...) -- David "Smith" a.k.a. Vid the Kid a.k.a.
