Unlimited for $60 isn't too bad (including line rental)

From which ISP?

The quality fluctuates wildly. If its $60 unlimited from a good ISP like iinet then it's a good deal, if it's with TPG or Dodo then it's not worth the hassle.

I'm not talking about residential lines. I'm talking about servers.

Right you are! I've had both colo in the US a number of years ago and current colo here in Australia. Couldn't agree more. Do you think that's due to the cost of "shipment" or just greedy men in the middle?

I have no idea. Haven't bothered to look into it.
