radius of around 200 kilometres.
Finally, they repeat the landmark search at this more fine-grained
level: comparing delay times once more, they establish which landmark

method. On average their method gets to within 690 metres of the target
and can be as close as 100 metres ­ good enough to identify the target
computer's location to within a few streets."
