Doesn't make sense. My AWS servers in Northern Viginia are being reported as being in Seattle area. And the route goes through London.

Agreed, most of the results I'm seeing don't make any sense at all. But IP geography has always been rather non-Euclidean.

Pretty funny to see what happens with www.1and1.com (my hosting provider). Boston to Wichita to Philadelphia... via Switzerland?

Results are not very accurate. For example, we are hosted in AWS us-west-1 (San Francisco), but because Amazon owns the IP it is routing to their HQ in Seattle Washington.

It does say on the site "Uses GeoLite data from MaxMind, March 2014."

So not only is the Maxmind data well over a year out of date it's [citation needed] likely to be the free dataset which is only a subset of the Maxmind purchasable data

A bit unrelated... but I find it interesting that the same person who programmed this (csvoss on github) is also the developer of two other projects trending on HN right now. Python oneliner: https://news.ycombinator.com/item?id=10114969 Retroactive data structures: https://news.ycombinator.com/item?id=10119065 Coincidence? Or is this just a slow hour on HN and good time to get submissions on front page?

Tell me about it. I've been having an exciting morning...

The oneliner was submitted early this morning, and that seems to have been the catalyst for the others.

Any reason why all CloudFlare connections bounce through TeliaSonera in Switzerland? It seems grossly inefficient to cross the Atlantic twice just to get from Massachusetts to California. Also, MIT -> Facebook : MA, MI, Singapore, Ireland, CA? How accurate is the data?

The data is as of March 2014, and therefore out of date -- I'm working on updating it right now. :) As I remember from when the data was fresh, sometimes you do get crazy hops across the Atlantic like that, though.

Maxmind data is also often just wrong, updated or not. As a hosting provider with a number of IP ranges, we have to deal with submitting corrections to them, Google, ip2location, etc. all the time. Not sure why none of them seem to use very accurate methods to discern IP location.

Since you're doing a traceroute anyhow, you'd be better off analyzing the transit hops, and specifically the city codes used in the reverse DNS entries.

Tried with my VPS in Singapore but it failed.

Edit: It can't be serious, the packets bounced from MA to MI then ended at VA.
