That's my point. Why was it blazing fast on iOS 7 release day when apples servers are being hammered by people downloading the new software and trying out the new siri, and yet now, when surely they are under a lot less load, is it so unreliable?
I'm in the UK like the OP if that helps. I notice another poster is in Sweden. Do siri requests from Europe go thru a different server than say requests from the US?
