It's fun to see how short the distance is when using tracerouting Akamai-hosted domains.

Slick. It also points out how inaccurate GeoIP is depending on which data source was used for that IP (eg. where the ISP is registered vs. where the endpoint may physically be).

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?

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

Not very accurate. Using owner's address apparently: AWS servers in us-east-1 are being reported as Seattle, where Amazon is headquartered.

Would it also be possible to add the times to each step? It would be interesting to compare the time vs reported distance. I suspect the times for some hops will be impossibly fast due to bad geo-ip lookups.

Yeah, the MaxMind data is as of March 2014 -- out of date. Sorry about that!

If you're interested in using the http://ipinfo.io API for this, so you don't have to worry about keeping your database up to date and you get additional details, let me know. I'd be happy to hook you up with a free unlimited plan specifically for this site.

Sweet, I'd be interested! Ping me with your contact information, and I can let you know once I've wired it up to use that.

The data is as of March 2014, and therefore out of date -- I'm working on updating it right now.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.

Why does 1.1.1.1 land you at google headquarters?

Whois says APNIC-LABS in Australia, but apparently this subnet is "routed briefly for passive testing".
