Majority of physical clues have been in USA and roughly around the East coast with some roughly placed in the West Coast. The other, international clues are based in proximity to capital cities with the exception of Australia's (New South Wales; East Coast)and Japan (Tokeshi, Okinawa Island).
The 2012 clues in Paris are literally around the corner from each other? Why place two clues in such close proximity? The South Korea clues are both in close proximity to underground stations so is it safe to assume one clue was posted before a quick train ride to post the next clue? The Seattle clues are also reasonably close to each other.

"I decided to look into the location of the Server Status IP address leaked from the Apache Server. The longitude and latitude of the IP point to Shinjuku Central Park in Shinjuku, Tokyo, Japan. I assume this is intended to be the location of Linode's data centre in Tokyo hosted by KDDI Corporation. A quick bit of research on KDDI and I discovered they have offices in Shinjuku (they're headquarters used to be based there) and, language barrier aside, I couldn't find a news story that said they had vacated, so it's reasonable to assume they still utilize the building. All of this, of course, means essentially nothing but I thought it was interesting to note that Linode offers data centres in America (4 in total), London England, and it's newest in Tokyo, Japan but Cicada 3301 opted to go with Asia Pacific hosting, when it is perhaps not unreasonable to suggest they are USA based, with 12 of the physical clues being placed in American locations, and the only Japanese based clue placed in Okinawa - Japanese Islands a considerable geographic distance from Tokyo!
All the other physical clues we're placed in capital cities: Australia (New South Wales - inner suburb of the capital city), Russia (Moscow - capital city), France (Paris - capital city), South Korea (Soeul - capital city) and Poland (Warsaw - capital city) with the only exception being Spain: Granada some 420km from the capital: Madrid? I don't think it's unreasonable to suggest that a international company would have offices in Capital cities across the world, but the only stumbling block being Granada which is not a particularly large metropolitan region in Spain?"
