OK for all those computer geeks out there.
A T1 is equal to a maximum transfer rate of 1.54 megabits per second.
A T3 is equal to a maximum transfer rate of 45 megabits per second.
There also much larger pipes like DS3's and OC3's.
A T1 would cost on average about 1K a month, a T3 a little more than twice that (I think).As you use or buy more bandwidth is will cost you more. Though you do gain economies of scale as you get larger.
I would think that this site is hosted on a T3 or larger, but that is only an assumption. The number of boards isn't really the factor it's the number of posts on the entire board. Posts with pictures generally take up more than 10 to 50 times as much bandwidth.
