Nice, thanks.On Sun Oct 13 2:39 +1000, Ron Stodden wrote:I get no mention of any "Internet2".A few years ago, in response to growing commercial traffic and concern that commercial traffic would destroy the scientific and educational traffic which the original internet was built for, a consortium of US univerities and related entities laid some very fast bandwidth that no one from the .com/.org/.net namespaces can use. For instance, last time I talked to my uni's techs, UMass has a total of 90 Mbps to Internet2 and 72 Mbps to the rest of the Internet. Thus, if the server I try to connect to is in one of the netblocks defined as part of Internet2, I effectively own a pair of T3s to a very nice backbone.
MIT seems well equipped - my traceroute to mit.edu ended:

So MIT has its own private backbone (internet2?) all the way to somewhere in californicus <g>.
