But, d#*(^&-it, they don't peer with ANS, and therefore we at NSF cannot
get to hosts like fnc.gov.  We, denizens of the NSF who have the good
fortune to have been caught in the institution's un-debated switchover to
PSInet.  Arghhh!

This is the way some hosts that are not yet forced through PSI *can* get to
fnc.gov:
