Ahh yes the thieving Scouser jokes...yawwwwn
A UPS failed causing the power cut. 15 minutes of disruption, no big deal and no significant delays.
Unfortunately we were unable to get our SSR feed back (remotely provided by NATS) and as far as I know it's still off. Neither NATS, BT, or our own TELS guys seem to know whats causing the problem. So we're Primary Radar only for the moment.
Yeoman - feel free to drag your arse over to ATC where we will happily sit you down in the radar room and answer your questions. Far more beneficial to us BOTH than through this forum.
