icm-dc-3.icp.net is a 7505, as is one of its counterparts on the other side of the Atlantic. All routers in Kansas City, Seattle, Cheyenne and Atlanta are 7513s, although they are not yet up and operational. There are a largeish number of 7513s deployed in another parallel network that is engineered out of our group. No points for guessing what that's for. :) Sean.
