Recently one of my customers was deciding between Co-Location at a major
provider and an in-house solution. Now most people will point to cost as a
factor but in this decision it was one of the last factors. The major
factors were of security, systems, functionality and administration. Without
going into all the why's, they made the decision to stay in house.
Are we moving towards a Net where you either have to be a big network or
be housed at a big network ? How does this help in the theories of diversity
and global reach. What happens when we move to IPV6 when every coffee pot in
the world has an address and most people have their own network ? Now I know
I don't have the answers but I do answer the calls when someone in northern
alaska can't get to the web site. Are we to the point where major ISP's can
now force us to co-locate at their facilities because of routing rules ?
Also how does this impact other countries as more routes and circuits show
up worldwide ? I am just wondering how this can get better as the route
tables keep growing. Is this a topic for the next nanog
