With reference to the traceroute above the node so-3-0-0.mp1.Berlin1.Level3.net (4.68.128.42) is in Germany, Europe considering the Round Trip Times (RTT) from the following monitoring nodes:

From

RTT

Stuttgart, Germany

14 ms

Karlsruhe, Germany

20 ms

However, Geoiptool suggests that the node is in US, Kansas. IP2Location suggests that its in Washington, DC.

 TULIP suggest that it is somewhere in Europe: (though it locates in Norway my hunch is that its somewhere closer to the intersection of the 4 circles)

Incorrect result II

Similarly the node ae-1-0.bbr2.Dusseldorf1.Level3.net (212.187.128.21) is in Germany considering the following RTTs:

From

RTT

Karlsruhe, Germany

8 ms

Stuttgart, Germany

13 ms

Zurich, Switzerland

13 ms

Warrington, UK

13 ms

London, UK

14 ms

Where as IP2Location suggests that its in UK and so does Geoiptool.

TULIP suggests that the router is in Netherlands which seems to more accurate:

Here are the RTTs from TULIP: (Netherlands RTT 3ms)

Incorrect Result III 

dsas3.ctio.noao.edu (139.229.17.44) is in La Serena Chile. GeoTool indicates it is in Tucson near the university. There are other hosts with the same domain name such as dsan3.ctio.noao.edu that are located in Tuscon. Unfortunately these hosts do not respond to pings. The traceroute indicates that the host is a long way away (> 300ms) from SLAC and probably in S. America (ampath is the connection point in Florida to S. America):
