If this is temporary does that mean we have to do 16000 NACRs
next week instead?

This will be a semi-full turn-off of the NSFNET backbone service.
The interconnects will remain in place.  Those interconnects
and the associated ASs are listed in a separate message to
the wider world.

If there are serious problems, please contact merit-ie and the 
on-call engineer will work with you (we don't do paperwork though).

We love to provide RA service everywhere and anywhere - it's just
a matter of somebody contracting for the service.  Any volunteers?

Thanks for the vote of confidence.
