For me it often comes close, but seems to be unable to converge on my actual location. It always ends up stuck south east of it. I am in San Francisco. The other passive geo system put a larger circle right around SF when I tried it. My guess is that none of the hosts it pings are to the north or west of me, or that they stick the hosts on a grid that doesn't wrap around to the nearest location, so it is biased towards the east/south.
