Three down: Mobile network customers could be receiving calls and have no idea

Three is down – and its users might have no idea. The network has stopped letting its users receive phone calls – though ringing out appears to work – but it hasn't notified anyone who uses it that it has broken. And it won't be telling them when it's fixed again, either. The problem means that people might be trying to make important calls to Three customers, but that they wouldn't have any idea. The I.F.O. is fuelled by eight electric engines, which is able to push the flying object to an estimated top speed of about 120mph.
