Perhaps we need some of these signs to hang around PPML:


AFAIK (someone please correct me if wrong) the critical infrastructure
policy has been in place since day 1 of ARIN.  Thus any critical
infrastructure provider has already had 11 years to get their own
block and not have this problem, and by most guesses has at least
two years to do so prior to their being a problem.

Were it just anyone, I would have little sympathy.  Being that it
is critical infrastructure, I have no sympathy.  If the thing really
is critical to the operation of the internet these sorts of
entanglements should have been removed long ago.  To say your
infrastructure is critical in the same sentence that you state you
have no contract or SLA for the items necessary to run it is rather

And the critical infrastructure has had 11 years to do just that,
and two more if they start now.  IMHO posting this policy now is
admission that they know of the problem well in advance, thus killing
any chance that I might have sympathy that a sale was "sprung on

I wonder what the judge will do when told "the community has provided
an option for the critical infrastructure provider to avoid this
situation for 13 years, and two years ago they tried to change the
community policy and were told to use the existing solution.  They
ignored this option, and rather came to you looking to overturn
community policy because they didn't plan properly."

This is an entirely separate point, and if you want to bring it up
I urge you to start a separate thread.
