This would explain why at&t claims that I am getting 300 Mbps every time I have them do a line check. I wonder if I would have the same issues if I had Google Fiber instead!?Rest assured you have 300 Mbps to the press release... For AT&T to really get this going they are going to have to improve their peering connections... It takes a lot longer to get that done that to turn up the speed on the local fiber which probably already has the hardware in place for 1gigabit and is simply capped at 300Mbps. These peering issues are probably why they limited it initially to 300mbits, it would be very obvious if they claimed 1Gb/s and delivered 80Mbps.
