I'm not entirely sure that it is, especially since I'd have expected it to restart yesterday morning (or maybe this morning - again, not sure when Jon does things). But looking at the munin graphs [1] I can see that the eth0 load is high, the CPU has been flat out earlier today, and the load average is spiking pretty high too. Mod_tile has a load average cutout where it stops trying to render tiles in the few seconds it normally gives renderd to respond (hence the usual few seconds before the "coming soon" logo appears. When that threshold is exceeded, mod_tile responds immediately with a 404 (and the osm.org Javascript shows the "coming soon" logo straight away). I don't know what the threshold is on tile.openstreetmap.org So a fair amount of speculations - the server is busy, but not that much more busy than it normally gets during the week, and I think it's triggering the mod_tile overload protection.
