Yep, all the traffic lights at the Sackville Road/Portland Road junction went off, and the power between St Patricks Road and Goldstone street was off... seemingly in that block. All the street lights were gone, all the houses were dark and all the cars were running amok! Bizarre. Back now though, I was fiddling with the damn alarm in my house (keep bleeping) and then it came back! Cracking timing on my behalf.
Saw flickering lights when walking through the industrial estate near the Tip, and Curry's. I wouldn't know of what it was like in my neck of BN3 though.
