[OT] Invalid host address

The "invalid" host URL is the same one all other users are contacting 
and is the domain of my client. Only an occasional user is getting this 
error when contacting the same URL(s), it works okay for almost everyone.

I'm pretty sure it's a machine-based issue, and my puny knowledge base 
points to some kind of system setup. I'd guess it's a wonky hosts file 
from what little I know about it, but it seems like his browser ought to 
fail too in that case. Or maybe it just doesn't like Amazon.
