Cheap IP transit
It seems that some of the big name Tier1s have come down a bit more in price lately. On commits of 200-500 megabits, GBLX can be bought for $20/mbit or less through a reseller, same with Qwest. Level 3 isn't much more expensive at $22-$25/mbit. Meanwhile, Cogent continues to prove that opex on their backbone is close to $6/mbit. If that holds true for those other Tier1s, pricing could continue to fall all the way across the board.
I absolutely love it. IP services are awesome because of their aggregation potential. Everything that once was, from telephone to television, can be reduced down to frames of IP and routed down a backbone. iSCSI and other types of distributed storage area networks call for big pipes, relying on IP as the transport medium. It's almost as cheap to pick up some inexpensive IP from a company like Cogent to offsite your SAN, as it is to buy an optical wave or SONET transport. These are definitely interesting times!
