I know there has already been two opinions about BYU's network connections, but I would like to clarify something as I was the one that managed the graphing of those connections and work in Network Engineering for 2 years.
Byu has connections from ELI, XO, UEN, I2, and iProvo. XO and ELI are the internet providers but all the connections are up all the time. Total bandwidth on and off campus is 250Mbit/sec. We used about 150 Mbit /sec during the day between Dec and April of '05 and some small amount at night (25 may be a good guess, I never payed that much attention to the troughs). Traffic is load balanced with BGP and both connections are active all the time. Local links run in active/passive mode using STP, appliances run in active/passive, but the internet links run in active/active. Just wanted to corroborate Brian's information.
