Hostmaster freeze Dec 28

Hi,

IST-Infrastructure Services operates the DNS servers and the backend
database that is used to provide Hostmaster services on campus. On
December 28, we will be switching the backend database service from an
in-house server to an IST-managed service. This will require
simultaneous changes to the back-end zonefile- and
configuration-generation scripts for the campus DNS servers, as well as
to the application that the Hostmasters (part of the IST Service Desk)
currently use.

Both database systems use the same DBMS, but to be on the safe side, I
am proposing that Hostmaster services be frozen during December 28th
(and through the immediately-following long weekend), in order for all
of the pieces to be put into place and for testing. Changes to the DNS
can be made on December 26 or 27, to take effect on the morning of
December 27 an 28, respectively. This allows us to back out of any
changes or correct any mistakes for users before starting the
switch-over. Other changes can be made on Wednesday, January 2. In
other words, this represents a one-day reduction in service from what
otherwise would have been the case during the holiday and curtailment
period.

Please feel free to contact me directly if this presents a problem for
you, and we can create a work-around. In the words of the Pennsylvania
Department of Transportation: "Temporary Inconvenience--Permanent
Improvement."
