How does the re-rendering process work? I was originally guessing that it followed an order, like left to right, top to bottom, then repeat for the next zoom level, but looking at one of my changes, slowly being re-rendered, it seems to be completely random squares that update. How does this process work, and how long does it usually take to render to the 5 mile zoom level? |

The whole world isn't pre rendered at all zoom-levels (else there would be a lot of boring blue ones). The higher zoom tiles are only rendered when first requested. See this question for a full explanation. |
