H-W;
There was once, and still technically may be, the "User Connectivity
Problems" (UCP) working group in the IETF Ops area that began a process for
coordination among the then regional NSFnet network's NOCs back in '90 or
so.
Much of the work accomplished by UCP on developing process for NOC-to-NOC
coordination is still valid, but the players have increased in number and
are re-inventing this wheel.
So, the Internet anarchy has been under attack for some time now. If there
is any interest (I know, hacking the configs is #1, formal coordination and
documentation are a distant #2) I'll go look up some of the documents.
