i have just communicated with the operators of gatekeeper.dec.com (with
whom ftp.isc.org shares a cage at PAIX) and was told two things.

1. HP plans to fully support gatekeeper (now that the merger is done),
   and has approved a 1-Terabyte expansion to its disk storage subsystem;

2. ftp.digital.com is no longer the same computer as gatekeeper.dec.com,
   it's a machine on the east coast somewhere.

i've asked whether there's any problems looming for ftp.digital.com, and
i'll report back here if i hear anything.  but gatekeeper.dec.com (which
i had a hand in creating back during my 1998-1993 stint at dec.com) is
absolutely safe from harm.
