I've always had trouble with non UK domains on non UK servers... so much so I refuse to move to the Azure Cloud because of this (even the EU servers are allocated a US IP Address).

I have tested .co.uk domains in the Azure cloud and these are fine.

So I would definitely re-host your .net domain back to the UK if possible, ASAP.
