Hi mate,
Who yanked your chain :-) As per my comments earlier, we are investigating, seems to potentially coincide with adding more 10 gig lags to our AKL->USA direct express route. We are working with our upstream provider to investigate as well as making some tuning changes on our side.
Once I know more, I'll share (as I do..) ;-)
Nick.
Ah apologies! Didn't see that part :) Thanks for investigating!
