Actually, what it's trying to tell you is that you're not in Peru. If you're 220 ms away from Singapore, you must not be in Columbia, since a speed-of-light transmission would take longer than that to make a round trip. For me, the most specific fix is provided by New York and San Francisco. Together, they can tell that I'm somewhere in the US, Canada, or Mexico. (But, of course, you could have figured that out from GeoIP.)
