I am doing some work on a network in central Illinois that is currently peering with Sprint and McLeod. They have a number of customers in the U.K. and they want to reduce latency to that part of the world.
Make sure they're not trying to reduce latency below the speed of light in fibre. Make sure that your client understands that they will never achieve the same latencies trans-Atlantic as they achieve within the state. We recently had to haul back one of our over-eager account managers who was trying to sell a low-latency solution that was about 3 times faster than the speed of light in fibre. BTW, the speed of light in fibre is roughly equal to the speed of electrons in copper and roughly equal to two-thirds the speed of light in a vacuum. You just can't move information faster than about 200,000 km/hr. --Michael Dillon
