If you draw a straight line from San Francisco to Amsterdam you will cross Iceland. [We have the] most customers from the US and Europe, so it makes sense to pick this geographical location.
I don't want to pick on them in particular, but this is a common misconception about how the internet works. Internet traffic doesn't follow great-circle routes, but instead follows the cables.  In the case of connections between the US, Iceland, and Europe, these are underwater cables:
This is only a diagram, and doesn't show exact routes, but you can see that Iceland has much better connectivity to the East than the West. A packet from the US to Iceland is probably going to first cross the Atlantic to mainland Europe, and then backtracking.
Running a traceroute from my RCN connection in Boston, this is what's
happening. I see packets going via
ae-2-3205.edge3.amsterdam1.level3.net, on their way to
126.96.36.199, an IP in Iceland.
We can also see this with ping times:
- Paris to Iceland: 52ms
- Boston to Paris: 108ms
- Boston to Iceland: 136ms
If you want to place a server "close" to both the US and Europe, trying to split the difference and put it in Iceland is worse than just putting it in Europe.
(Separately, it's also not helpful to think of a domain as having to be
hosted from only one place. You can configure DNS so the domain will
resolve to different IP addresses in different parts of the world, and
you can handle user requests as closer to the user as possible.
Requests like "please give me
script.js" or "please record
that someone visited
example.com" can easily be handled by
multiple servers around the world.)
 This isn't completely true: there are non-cable links, but cables carry the vast majority of internet traffic.
