Nice thanks, looks like it's on the old 2degrees side, may also be isolated a BNG (subscriber termination) in a specific area also.

Apologies for the noise, I didn't realise until now that the 2degrees and Vocus forums has merged. I naively assumed you were on Vocus as well. I'll be sure to read properly next time! :)
