Try to remember not to top-post, please. It makes it hard for others to 
read the thread.

I don't know, but it kind of has a DNS feel to it, possibly. Nothing 
concrete to go on, just past experience when I see network and I know 
the network is fine... I think DNS. Maybe reverse resolution of your 
private IP address space assuming your requests are being made to/from 
private addresses? That's really just a shot in the dark because we 
don't have much to go on. I'd start thinking network and DNS, put in 
some debug, see what if anything is timing out.
