Re: How Consolidation is Eroding Internet Resilience

[Stephen Satchell via NANOG <nanog () lists nanog org>]

The whole ARPAnet experiment was based on the idea of a network of 
geographically distributed nodes, heavily interconnected.  What the 
thing we call the Internet today condenses those nodes, so the node 
count falls to the point that failures are more catastrophic.

Further, the administration of the nodes is starting to coalesce, so a 
single mistake takes out multiple nodes.  MBAs are killing the Internet 
that we used to know.  We are going backwards in time, when networks 
were star networks with a common hub, instead of autonomous network of 
networks.

Another allied issue is the A&R of network equipment suppliers.  Fewer 
suppliers, plus more chance of cross-contamination by bad code, bad 
documentation, and bad training.
