Anssi is right, I don't see anywhere that they host in mexico.

All other geo IP lookup tools point to Denver US.

Even using maxmind, It tells us ISP and Organization is fdcservers.net

If we look here: https://www.fdcservers.net/network.php

There is no mention of Mexico, but there is mention of Denver, US, where other Geo IP's point to.

If you go directly to, it points to http://litehost.co/ Which is located in Chicago, IL, US where traceroute from any location points to.

Their website says "Our Tier 3 datacenter is located in Chicago, IL ensuring 99.9% uptime." Nothing about other locations.

Finally traceroute mentions host-engine, http://host-engine.com/network.htm, Again only mentions of either Chicago and Denver

"Our servers are located in Tier III datacenters on Denver, Miami and Chicago, connected to 1gbps uplink, guaranteeing 99% uptime and the best ping."

I think we can conclude that, the server is actually located in US.

I'm sorry my example of a Mexican IP address was not good enough for
you. That was not a mirror's IP address, but that is probably not
relevant. Softlayer does peer with some Mexican providers, but
apparently not with the ones you are using. Which Mexican ISPs are you
peering with?

But the thing is, I can find tons of examples where traceroute to your
server goes through U.S., but none that would show that it would go
directly from a host in Mexico to your mirror. In this situation, I
believe the burden of proof is on you. Extraordinary claims require
extraordinary evidence, as the saying goes.

Please find me an example traceroute which shows true Mexico <-> Mexico
connectivity and then I can have a closer look. This would also need to
be something that I can verify myself -- examples of such verifiable
claims include ISPs' looking glass websites, where I can give an IP
address and the website will run a traceroute to the specified address.

I would also like to reiterate that I don't particularly care where the
servers itself are located, but where they are exposed to the rest of
the Internet. If you route all the mirror's traffic through some VPN to
a U.S. IP address, it is a U.S. mirror from our point of view and not a
Mexican mirror.
