<div dir="ltr"><div>What's wrong with the /status URL on tiles? It works for <a href="http://osm.org">osm.org</a> and Mapquest Open. Doesn't seem to work for cloudmade but then I don't think your plan would work any better. From what I've seen, cloudmade does generally update their data relatively quickly but their tile server is either overloaded or configured in such a way that it is a pain to actually ensure that a given tile is freshly rendered. Sometimes I have seen fresh tiles right next to stale ones. So you changing data somewhere in the middle of the ocean will have no bearing on the freshness of a tile served up 5,000 miles away.</div>

For example, are Cloudmade and MapQuest tiles updated? Idea: add visible timestamp ("watermark", "microprint") using fake ways to the global map, so it would be rendered with more or less any possible layout, but only if you know from where to look for it. Maybe near null island. Or my home.<br clear="all">
