The England to Washington DC is interesting since VTrace, Maxmind and undns (orange line) give very different results for the target. Despite Sofia University advertising itself as being in Palo Alto the web server is actually near Washington DC. Also the route does not go from London to Paris as indicated by Maxmind.
For the Pakistan to hotmail.com (Micorsoft WA) undns gets off track and goes to Australia. Since hops 9-13 do not respond to pings, VTrace correctly gets hop 6 as being in Karachi (while Maxmind puts in the middle of Pakistan), however VTrace loses track when after getting to Franfurt Germamy, while Maxmind gets the end destination as being Microsoft's home of Redmond Washington.
Complementarity of VTrace and MaxMind
