It is a bit frustrating having the random speeds, but I guess they are still in early stages in gigabit fibre, so I hope in the next few weeks :| we'll start to see an improvement on the reliability of the speeds.
are you sure it's not anything on your end? i've had a gigabit service from snap/2d for years and it's always been solid. I am in Auckland though, might be a different story if you're somewhere remote.
