Quite, but how do I diagnose it?
Do you run DNS on your Lan or just forward DNS requests through your router(s). If you have local DNS then I suggest you set that up to point zbmc.eu to the local address of your web server rather than the internet facing one.
The reason this is happening is that quite possibly the gateway for whichever connection zbmc.eu resolves to cannot route to itself. So if your request happens to go out on that gateway (assuming it is truly random and I am still not sure how you have that set up) then it is unable to form the circular route to connect back to your webserver through port forwarding or DMZ or however you have that set up.
When your request goes out via the other ADSL connection it will work just like it does for anyone else looking at those pages (they load reliably for me)
